a. Does the sample provide evidence that there is a difference in calorie content for ales and IPAS? Assume the conditions for using a t-test are satisfied. Use a significance level of 0.05 for the hypothesis test.
b. If the test had been to determine whether the mean for IPAS is significantly larger than the mean for ales, how would this change the alternative hypothesis and p-value? Test this hypothesis and write the conclusion for the test.
b. If the test had been to determine whether the mean for IPAS is significantly larger than the mean for ales, how would this change the alternative hypothesis and p-value?
The alternative hypothesis would change from µ,
H2 to µ1
H, and the p-value would
