A ssume that you want to test the claim that the paired sample data come from a population for which the mean difference
is#d = 0. Compute the value of thet test stati stic.
10) X 12 3 12 2 12
95 837
10)
A) t = 0.578
B) t = 0.415
C) t = 2.890
D) t = 1.292
Determine the deci si on criterion for rejecting the null hypothesis in the given hypothesis test; i.e., describe the values of
the test stati stic that would result in rej ection of the null hypothesi s.
11) Suppose you wish to test the claim that µd, the mean value of the differences d for a population of
11)
paired data, isdifferent from 0. Given a sample of n = 23 and a significance level of a = 0.05, what
criterion would be used for rejecting the null hypothesis?
A) Reject null hypothesis if test statistic> 2.074 or < - 2.074.
B) Reject null hypothesis if test statistic> 1.717 or <- 1.717.
C) Reject null hypothesis if test statistic> 1.717.
D) Reject null hypothesis if test statistic> 2.069 or < - 2.069.
