11. What is your conclusion in each of the following scenarios?

Solution

a. p-value is 0.014 < 0.05, hence reject the claim of p=0.34

b. test statistic Z = -1.75 > -2.58(1.75<2.58 at 1%(0.01) level, hence accept the claim

c. chi - square test statistic value at (22-1) 21 d.f and 0.05 level is less than the critical value i.e., 22.6 < 32.671, hence accept the claim
