for the hypothesis ho p 03 versus ha p does not equal 03 and

for the hypothesis, ho: p =0.3 versus ha: p does not equal 0.3 and a test statistic equal to 1.56, what is the p-value?

Solution

This is a two tailed test.

Thus, the two tailed P value if z = 1.56 is twice the left tailed area of z = -1.56. Thus, by table/technology,

P = 2*0.059379941 = 0.118759881 [ANSWER]
