PSYC 201 Statistics

Question #1


Joe and Katy are enrolled in a psychology course. In this course, the average grade is 71 and the variance of the grades is 81. Assume that the grades are perfectly normally distributed.


  1. Joe’s final grade was 53. What percentage of students in the course had a grade lower than Joe?


  1. Katy had a final grade that was 1 standard deviation above the mean. What was her final grade?


  1. What percentage of students in the course had a higher grade than Katy?


  1. What percentage of students in the course had a grade in between Joe and Katy?




Question #2


In a recent survey, UVic students were asked to rate their opinions of “Cheese” pizza and “Pepperoni” pizza.  The ratings were on a “1” to “10” scale where “1” indicates a strong negative opinion and “10” indicates a strong positive opinion.  The histograms of the ratings are shown below:


  1. Compute and report the range, mean, median, and mode of the Cheese pizza ratings


  1. Compute and report the range, mean, median, and mode of the Pepperoni pizza ratings


  1. Do you think the two histograms show equal or unequal variability? Why or why not? (Hint: See variance formula below.)




Question #3


Imagine a researcher is interested in whether psychology majors are better at recognizing facial expressions than computer science majors.  The t-test formula (shown below) is the inferential statistic for determining whether this experiment produced “significant” difference between the two groups.


As a general rule, an experimenter would like to obtain a large t score that is greater than 1.96. What are the three factors that determine the magnitude (size) of the t score?




Question #4


Austin is a student in the Psych 201 course.  Based on personal observations, Austin thinks that left-handed individuals have a larger reading vocabulary than right-handed individuals. To test this hypothesis, Austin administered the North American Adult Reading Test (NAART) to a group of university self-identified left- and right-handed students.  The NAART is comprised of 50 written English words which all have atypical spellings (e.g., “aisle”, “chord”, “gauge”).  Previous research has indicated that performance on the NAART predicts reading ability and general verbal intelligence.



4a.) State the research (alternative) and null hypotheses in Austin’s study.


4b.) Austin averages the scores and finds that the mean score for the left-handed group was 85% correct and the mean sore for the right-handed group was only 65% correct.  Should Austin conclude that the left-handers are statistically better than the right-handers in their reading vocabulary?  Why or why not?  Please give a complete explanation for your answer.


4c.) Draw one diagram showing where the 20% mean score difference between the left-handed and right-handed groups is significant.  Explain why the diagram shows a significant difference between the two groups.


4d.)  Draw another diagram where the mean score difference of 20% between the left-handed and right-handed groups is not significant. Explain why the diagram shows that the difference is not significant.


4e.) State and explain the Type 1 and Type 2 errors that Austin might commit in the reading study.

This is a finance one, years ago you invested in 7 acres of land at the edge of town with the
thought of expanding your business on the property sometime in the future. In the years since
you bought the property the city expanded around your acres and now you see an opportunity
to sell your property. You have also started a different building project that you do not have
fully funded and will need to borrow money unless you are able to sell the property on the
edge of town.
The building project is being done over several years and has a $19,000,000 price tag. You have
secured 12 million so far, can restructure another 2 million dollars with internal borrowing, but
are counting on 5 million from the sale of the land to avoid borrowing that amount. You have
not received any offers for the full amount but have received offers around 3 million but feel
that is far below the value of the land and you do not want to give it away. At some point you
will need to borrow the 5 million as the project is completed early in 2023. You estimate a
business loan will have an interest rate of around 6 percent annually. Prepare a business
proposal using financial functions like pmt or fv to predict when you would be better off taking
a low offer (Scenario Manager might be a good tool) rather than waiting for the land to sell at
your asking price. You should show what the loan is going to cost over time vs. what it would
cost if you took a lower offer – I would suggest you model it based on a sale of both 3 million
and 4 million. Charts/graphs along with payment plans showing interest and principal over
time to help me understand when it starts costing more to wait for the full offer vs. taking a
lower offer now. If you think you can secure a lower interest loan you could show the costs
based on lower (or higher) rates as well.

MAT 510 Business Statistics

The research department of an appliance manufacturing firm has developed a new bimetallic thermal sensor for its toaster. The new bimetallic thermal sensor can sense the temperature of the bread and move the lever arm to activate the switch. The research department claims that the new bimetallic thermal sensor will reduce appliance returns under the one-year full warranty by 2%–6%. To determine if the claim can be supported, the testing department selects a group of the toasters manufactured with the new bimetallic thermal sensor and a group with the old thermal sensor and subjects them to a normal year’s worth of wear. Out of 250 toasters tested with the new bimetallic thermal sensor, 8 would have been returned. Seventeen would have been returned out of the 250 toasters with the old thermal sensor. As the manager of the appliance manufacturing process, use a statistical procedure to verify or refute the research department’s claim.


Create 8–10 slides, including a cover and a sources list, for a presentation to the director of the manufacturing plant in which you:

  1. Summarize the problem with the appliance manufacturing firm’s toaster.
  2. Propose the statistical inference to use to solve the problem. Support your decision using a scholarly reference.
  3. Using Excel:
    • Develop a flowchart for the proposed statistical inference, including specific steps.
    • Compute all statistical calculations.
  4. Place your flowchart in a slide.
  5. Determine if you can verify or refute the research department’s claim.
  6. Choose sources that are credible, relevant, and appropriate. Cite each source listed on your source page at least one time within your assignment. For help with research, writing, and citation, access the library or review library guides.

Reflect of what you have learned in week 1-7 of the course.  Answer the following questions in 250-300 words based on your own individual learning experience. There should be no collaboration with other students.

    1. How do you apply your previous course units into the data exploration, management and governance covered in Unit 5-7?
    2. How would you apply what you learned so far in this course since Unit 5-7 to your professional life if asked to work with data?
    3. What’s your greatest “take away” learning so far in this course for regarding health care data (collection, management, information to knowledge) ? Why?
    4. What unanswered questions remain?





Unit 7: Summary


The course began discussing Health Information Sysems as the tool for data collection, storage and retrieval. Another role is to convert data to information and knowledge. In other units we addressed the importance of data literacy, quality and security of data. In Unit 5 all students had the hands on simulation with an I2B2 database and given the opportunity to present  individuals conversion of data into information and knowledge. Each of you has shown that there is not one way in which the task can be done. In the final unit we took a closer look at governance and data management which is dependent on data literacy, data quality and security.
