An economist wants to perform a hypothesis test to compare the mean salaries of faculty in private
institutions and public institutions.
Independent simple random samples of 15 faculty members in private institutions and 15 faculty members
in public institutions yielded the data in the table below.
You are encouraged to use Excel Calculators.
a. Procedure:
Sample Size
Average ($1000)
Standard Deviation ($1000)
Et
At 1% significance level, do the data provide sufficient evidence to conclude that the mean salaries for
faculty in private institutions are greater than the mean salaries for faculty in public institutions?
Matched Pairs (Paired) t test
Two-Sample t test
One-Sample t test
b. Assumptions: (select everything that applies)

b. Assumptions: (select everything that applies)
Matched Pairs (or Paired) samples
c. What is the claimed (or hypothesized) value in this test? 0
d. Is this a one-tail or two-tail test?
one-tail
two-tail
of
Sample sizes are both greater than 30
Population standard deviations are unknown and not assumed equal
Independent two samples
Population standard deviations are known
Population standard deviations are unknown but can be assumed equal
Simple random samples
Populations have Normal distributions
e. Compute the P-value of this test. (Round to 3 decimal places) P-value is 1

f. Is the P-value less than or equal to the significance level? yes

Hint: Double check if you selected the correct answer based on one-tail versus two-tail p-value.
Round properly to 3 decimal places
After rouding to 3 decimal places, if you answer has 0 after dot, then entre those too for the
