Treatment Placebio Pz 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 random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete all parts below. Use a 0.10 significance level. 25 2.12 Test the claim that the two samples are from populations with the same mean What are the null and alternative hypotheses? O A. HO:141 #142 OB. HO: P1 H2 Hy Py # P2 The test statistic, t, is (Round to two decimal places as needed.) State the conclusion for the test. O A. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that the two samples are from populations with the same mean O B. Reject the null hypothesis, There is sufficient evidence to warrant rejection of the claim that the two samples are from populations with the same mean O C. Fail to reject the null hypothesis. There is sufficient evidence to warrant rejection of the claim that the two samples are from O D. Fall to reject the null hypothesis. There is not sufficient evidence to warrant rejection of the claim that the two sample
