Test of claim for the statement made for a given paired sample:

Suppose you want to test the claim the paired sample data given below come from a population for which the mean difference is mean d = 0.

50	80	84	61	59	82	61
71	57	84	93	81	94	60

Use a 0.05 significance level to find the following:

(a) The mean value of the differences d for the paired sample data d=

(b) The standard deviation of the differences d for the paired sample data s_d=

(d) The positive critical value t =_

(e) The negative critical value

(f) Does the test statistic fall in the critical region?

A. No
B. Yes

(g) Construct a 95% confidence interval for the population mean of all differences x - y.
