Treatment Place 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 parts (a) and (b) below. Use a 0.05 significance level for both parts. H1 in 29 39 2.31 2.69 0.99 O A. Fal to 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 0.69 mean. O B. Reject the null hypothesis. There is not sufficient evidence to warrant rejection of the dlaim that the two samples are from populations with the same mean. OC. Fai to 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.
