7. A researcher is asked to determine whether or not a productivity
objective (in dollars) of better than $75,000 per employee is
possible. A productivity test is done involving 20 employees. What
conclusion would you reach? The sales results are as follows:
a. 28,000 105,000 58,000 93,000 96,000
b. 67,000 82,500 75,000 81,000 59,000
c. 101,000 60,500 77,000 72,500 48,000
d. 99,000 78,000 71,000 80,500 78,000
8. Assume you have the following data:
H1:200,S30,
n
64, and
__
X
218. Conduct a two-tailed hypothesis test at
the 0.05 significance level.
9. If the data in question 8 had been generated with a sample of
25 (
n25), what statistical test would be appropriate?
10. The answers to a researcher’s question will be nominally scaled.
What statistical test is appropriate for comparing the sample data
with hypothesized population data?
