You are involved in an analysis of the relationship between the cost of chemicals
used in a manufacturing process and the volume of production. You have
collected the following production usage data over the last five years and
adjusted it for the effects of inflation:
Table 3.8—Production Usage Data
Production Units Chemical Costs
4 $800
15 $1,200
20 $1,400
30 $1,800
50 $2,000
1. Estimate the cost to produce 26 units. (Hint: Use the regression template.)
2. Determine the coefficient of determination (r2).
3. Determine whether to use this analysis for estimating purposes.
* The cost is dependent on the
units produced. When using
the regression spreadsheet, be
sure to put the numbers in the
right columns for dependent
and independent variables!
In other words, is the r-squared
value above 80%, indicating a
reliable relationship between the
variables?
EXERCISE #2: JOHNSON IMAGING, INC.
You have obtained the following Johnson Imaging data related to MRI
production:
Table 3.9—Johnson Imaging Data
Model Display
(pixels)
Unit Cost
A 5,200 50,000
B 6,300 70,000
C 9,000 160,000
D 7,500 140,000
E 13,000 225,000
Assuming that pixel display is the independent variable and cost the
dependent variable, use the regression sheet to document the data.
1. What is your estimate of the cost of an MRI unit that displays a 12,500-pixel
image?
2. Determine the coefficient of determination (r2).
3. Determine whether to use this equation for estimating purposes. (yes/no)
EXERCISE #3: VOLUME CHEMICAL
You are involved in analyzing the relationship between the cost and the volume
of production. You have collected the following inflation‐adjusted data:

1,450 $64,450
1,500 $66,000
1,750 $69,438
2,100 $73,410
2,150 $75,720
3,050 $79,375
1. Estimate the cost to produce 2,000 units.
2. Determine the coefficient of determination (r2).

2. A well-known analysis in Malcolm Gladwell’s book Outlier argues that the best hockey players are
more likely to be born earlier in the year presumably because this gives them advantages in the youth
hockey leagues. We are interested in checking whether there is a similar effect in basketball.
(a) The data set Basketball Ref BDays.txt contains information for a large sample of professional
basketball players listed on the http://www.basketball-reference.com web site. Use the table
or dplyr::count function to calculate how many players were born in each month. Draw an
appropriate plot.
(b) Perform a ÷2 test to see if the players are equally likely to be born in any month.
(c) In order to focus our attention on modern players, repeat this analysis with only those players
that were born after 1/1/1955. (also use this smaller data set for the following questions.)
(d) To be more careful, we should realize that more people are probably born in January than February
just because there are more days in January. Perform a ÷2 test where the null hypothesis is that
the probability of each month is proportional to the average number of days in that month.
(e) Going even further, it seems that some months generally are favored over others for having babies
(summer births are more likely). We should probably compare our basketball player data to the
following probabilities from the CDC.
Month Jan Feb Mar Apr May Jun
Prob. 0.0815 0.0752 0.0837 0.0816 0.0860 0.0813
Month Jul Aug Sep Oct Nov Dec
Prob. 0.0883 0.0892 0.0866 0.0849 0.0787 0.0830
Perform a ÷2 test to see if the basketball player data has the same distribution.
(f) Interpret your results. Is there significant evidence at an á = 0.05 level that professional basketball
players are born earlier in the year than the normal population?

Assessment question

Which of the following are stages of the cohesion-tension theory of water transport in plants? Select all that apply.

This tension extends from aboveground leaves to belowground roots, and the cohesion between the molecules in these columns pulls water from the soil into the roots.

Water evaporates from leaves and other aboveground plant parts via open stomata.

Evaporation exerts tension and pulls on the narrow columns of water that fill xylem tubes.

Assessment question

Transpiration

consists of the evaporation of water from aboveground plant parts.

Translocation

consists of the movement of organic molecules through phloem.

Assessment question

Which of the following are stages in the translocation of sugars through the phloem? Select all that apply.

Not all correct answers selected

At a sink region, sugars move from sieve elements into sink cells, and water follows by osmosis.

The increase in solute concentration causes the fluid in the sieve element to become hypertonic, and this causes water to move by osmosis into the sieve element.

At a source region, sugars move into a companion cell, then into a sieve element.

The influx of water into the sieve element generates turgor pressure, which pushes the fluid through the sieve tube toward a sink region with lower turgor.
