Treatment Placebo A study was done using a treatment group and a placebo group. The results are shown in the table. Assume that the two samples are independent simple H random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) n and (b) below. Use a 0.01 significance level for both parts. H1 H2 37 29 2.36 2.67 0.53 0.93 .... a. Test the claim that the two samples are from populations with the same mean. What are the null and alternative hypotheses? B. Ho: H1 = H2 O A. Ho: H1 # H2 H: H1 H2 H: H12H2

Question

Q2-Please help me find the Test Statistics, P value and also with the last part of the question where it says " b " construct a cofidence interval suitable for testing..... same mean BMI . 

Thanks in advance.

The test statistic, t, is (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State the conclusion for the test. O A. Reject theuhypothesis There is not sufficient evidence o warrant rejectionof th claim that the twamples are from poputions wihe same mean. C B. Rejec the pull hypothesis. There is sufficient evidence to warrant rejection of the laim that thewo samples are from popyaions ith the same ean. CC Fail to reject the null hypothesis. There ie hot sufficientevidenceto warrant rejetion ofe claim tha the two samples are from populatios with the same mean. D. Fail to reiect the null hypothesle. There is sufficient evidence to warrant rejection of the claim that the two samples are fom populations with the samemean. b. Construct a confidence interval suitable for testing the claim that the two samples are from populations with the same mean. (Round to three decimal places as needed.)
