Question
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 populations are normally distributed.
Claim: H, 20; a = 0.05. Sample statistics: d = -2.2, s, = 1.5, n=14
Identify the null hypothesis by writing its complement.
O A. Ho: Ha #0
Ha: H = 0
O B. Ho: Hg s0
Hgi Hg>0
O D. Ho: Ha <0
OC. Hg: Ha =0
OF. Ho: Ha>0
E. Ho: Ha 20
H: H <0
The test statistic is t= -5.49.
(Round to two decimal places as needed.)
The critical value(s) is(are) t, = - 1.77
(Round to two decimal places as needed. Use a comma to separate answers as needed.)
V the rejection region,
V the null hypothesis. There
V statistically significant evidence to reject the claim.
Since the test statistic is
