A researcher wants to determine how employee salaries (in thousands) at a certain company are related
to their length of employment (in years). The researcher randomly selects 8 employees and obtains the
following data:
|
Salary |
57310 |
57380 |
54135 |
56985 |
58715 |

- Compute the correlation coefficient (r) and say what it describes.
- Provide the regression equation for this data (label your variables – don’t use y and x).
- Calculate the coefficient of determination (r2) and give its interpretation.

A researcher wants to determine if the average salaries for
professors at all public and all private universities are
different. He randomly selects 30 professors from public
universities and independently 30 professors from private
universities. The data are in thousands of dollars. The statistics
are given below. Test the claim that the average salaries for all
professors at public and private universities are different. Use α
= 0.05 and fully justify!

A medical researcher wants to determine if the average hospital
stay after a certain procedure is less than 11.87 days. The
hypotheses for this scenario are as follows: Null Hypothesis: μ ≥
11.87, Alternative Hypothesis: μ < 11.87. If the researcher
randomly samples 25 patients that underwent the procedure and
determines their average hospital stay was 10.6 days with a
standard deviation of 6.724 days, what is the test statistic and
p-value of this test?

1. A researcher wants to determine whether the time spent online
per day is related to gender. A random sample of 315 adults was
selected and the results are shown below. Test the hypothesis that
the time spent online per day is related to gender. Use α =
0.05.
Identify the null hypothesis, Ho, and the alternative
hypothesis, Ha.
Determine whether the hypothesis test is left-tailed,
right-tailed, or two-tailed.
Find the critical value(s) and identify the rejection
region(s).
