Question

Consider testing H0: (p1-p2)=0 versus a two-tailed research hypothesis (H1: (p1-p2) not equal 0). Suppose you obtain a z test statistic equal to -2.37. Recalling that researchers typically report the best significance level reached among the conventional significance levels, the difference is statistically significant at a _____ percent level. (Type either 1, 5 or 10 to correctly fill in the blank.)

Answer 1

Answer to the question is 10 percent level.

This is because , at 10 percent level , the level of significance is 5 percent each for a two tailed test which gives a value of z of less than -1.645 for a statistically significance attainment. Both the other values of 1 percent and 5 percent does not give a statistically significant value.
