A recent study of debt among college graduates reported that the average debt accumulated by graduates of private colleges
was $38,200, with a sample standard deviation of $2,054, while the average debt accumulated by graduates of public colleges
was $11,700, with a sample standard deviation of $2,075. The sample sizes were 70 and 180, respectively. Complete parts a
and b below.
Conduct a hypothesis test to determine if the average college debt for bachelor of arts degree recipients is at least $21,000
more for graduates from private colleges than from public colleges. Use a significance level of a = 0.025.
a. Let x, = $38,200 and x, = $11,700. State the null and alternative hypotheses.
O B. Ho: H1 - H2s $21,000
HA: 41-H2 > $21,000
O A. Ho: H1 -H2 > $21,000
HA: H1- H2s $21,000
O C. Ho: H1-H2 < $21,000
HA: H1- H22 $21,000
O D. Ho: H1-H2 = $21,000
HA: H1- H2# $21,000
O E. Ho: H1-H2 2 $21,000
HA: 41- H2< $21,000
O F. Ho: H1- H2# $21,000
HA: H1-H2 = $21,000
b. Calculate the test statistic.
The test statistic is.
(Round to two decimal places as needed.)
c. Calculate the p-value.
The p-value is

d. State the conclusion for this hypothesis test.
O A. Do not reject Ho. There is sufficient evidence at the a= 0.025 level of significance to conclude that graduates of
private colleges have at least $21,000 more in college-related debt.
B. Reject Ho. There is not sufficient evidence at the a = 0.025 level of significance to conclude that graduates of private
colleges have at least $21,000 more in college-related debt.
OC. Reject Ho- There is sufficient evidence at the a = 0.025 level of significance to conclude that graduates of private
colleges have at least $21,000 more in college-related debt.
D. Do not reject Ho. There is not sufficient evidence at the a = 0.025 level of significance to conclude that graduates of
private colleges have at least $21,000 more in college-related debt.
