test the claim below about the mean of the differences for a population of paired data at the level of significance a. assume the samples are random and dependent, and the population is normally distributed.

claim: ud=0; a=0.01. sample statistics: d=2.9, sd =8.71, n=8

A) identify the null and alternative hypothesis.

B) the test statistic t=?

C) the critical values are t0=?

D) sincebthe test statistic is (not in/ in) the rejection range, (reject/ fail to reject) the null hypothesis. there (is/is not) statistically significant evidence to reject the claim.
