Determine the test statistic.
t= 12.07 (Round to two decimal places as needed.)
Determine the P-value.
P-value = .000 (Round to three decimal places as needed.)
Should the hypothesis be rejected?
Reject
the null hypothesis. The evidence does
suggest that community college transfer students take longer to attain a bachelor's degree at the a= 0.10 level of significance.
d) Construct a 99% confidence interval for Poommunty cologe " Hno transfer to approximate the mean additional time it takes to complete a bachelor's degree if you begin in community college.
The confidence interval is the range from
to
(Round to three decimal places as needed.)
