Suppose that you are to conduct the following hypothesis test for matched data:   H0:μd=0 H1:μd≠0 For a sample of 16, it was found that d¯=−1.9 and sd=4.59. Determine each of the following: The value of the test statistic:   For ?α = 0.025, the final conclusion is A. There is enough evidence to say that ??=0μd=0 B. There is not enough evidence to say that ??=0μd=0 C. There is enough evidence to say that ??≠0μd≠0 D. There is not enough evidence to say that ??≠0μd≠0.

Just need part d

You wish to test the following claim (H) at a significance level of a = 0.005. H₂:1 = μ₂ Ha: M1 M₂ You believe both populations are normally distributed, but you do not know the standard deviations for either. However, assume that the variances of the two populations are equal. You obtain a sample of size n₁ = 20 with a mean of ₁ = 60.9 and a standard deviation of SD₁ = 6.2 from the first population. You obtain a sample of size n₂ = 15 with a mean of 2 = 76.9 and a standard deviation of SD2 = 18.6 from the second population. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... O less than (or equal to) a Ogreater than a
