The sample mean = 2.50 and the sample standard deviation = 0.8302.
The distribution can be written as X ~ U(1.5, 4.5).
a. What type of distribution is this?
b. In this distribution, outcomes are equally likely. What does this mean?
c. What is the height of f(x) for the continuous probability distribution?
d. What are the constraints for the values of x?
e. What is P(2 < x < 3)?
f. What is P(x < 3.5| x < 4)?
g. What is P(x = 1.5)?
h. What is the 90th percentile of square footage for homes?

Researchers studied the effect of a houseplant fertilizer on
radish sprout growth. They randomly selected some radish seeds to
serve as controls, while other were planted in planters to which
fertilizer sticks were added. The following table shows
data on the heights of plants (in cm) two weeks after
germination.

Listed in the accompanying data table are student evaluation
ratings of courses and professors, where a rating of 5 is for
"excellent." Assume that each sample is a simple random sample
obtained from a population with a normal distribution.
a. Use the 93 course evaluations to construct a 98%
confidence interval estimate of the standard deviation of the
population from which the sample was obtained.
b. Repeat part (a) using the 93 professor
evaluations.
c. Compare the results from part...

We wish to determine the impact of Specification Buying, X11, on
Satisfaction Level, X10. To do so we will split the Hatco data file
into two separate data sets based on the Specification Buying, X11.
This variable has two categories:
1=employs total value analysis approach, evaluating each
purchase separately;
0 = use of specification buying.
Sort the entire Hatco data set based on Specification Buying.
This will create two separate groups of records. Those records with
X11 = 0 and...

Use the data in Bank Dataset to answer this question.
Construct a 95% confidence interval for the mean increase in
deposits. Note that the population standard deviation σ is not
known in this case. Instead the sample standard deviation s should
be calculated from the sample and the t distribution should be
used.
2. What is the margin of error at the 95% confidence level?
