1) What are the null alternative hypothesis?
2) what's the test statistics?
3) what's the P-value

4) State the conclusion

5) construct a confidence interval suitable for testing the claim that the two samples are from populations with the same mean

6) Does the confidence interval support the conclusion found with the hypothesis test?

Extracted text: 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 random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) n below. Use a 0.01 significance level for both parts. 41 27 32 2.37 2.68 0.94 0.66 a. Test the claim that the two samples are from populations with the same mean.
