Please see below. I need help with these.
Transcribed Image Text:You randomly select 14 student cars and find they have a mean age of 7.3 years and a standard deviation of 3.6 years. You also
random select 18 faculty cars and find they have a mean age of 5.3 years and a standard deviation of 3.3 years.
1. Use a 0.01 significance level to test the claim that student cars are older than faculty cars.
(a) The test statistic is
(b) The P-value is (give to 4 decimal places):
(c) Is there sufficient evidence to support the claim that student cars are older than faculty cars?
A. No
B. Yes
2. Construct a 99% confidence interval estimate of the difference µ, - Hr, where µ, is the mean age of student cars and uf is the mean
age of faculty cars. (give answers to at least 3 decimal places)
