Confidence interval :-
t(α/2, DF) = t(0.01 /2, 63 ) = 2.656
DF = 63
99% confidence interval is ( -1.523 , 5.626 )

3. Test the indicated claim about the means of two populations. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use the P-value method. A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure, measured in mm Hg, by following a particular diet. Use a significance level of 0.01 to test the claim that the treatment group is...
