Consider the following null and alternative hypotheses:

H0: p=0.79versusH1: p does not equal 0.79

A random sample of600observations taken from this population produced a sample proportion of0.84.

a.If this test is made at a2%significance level, would you reject the null hypothesis? Use the critical-value approach.

Enter the critical values in increasing order. Round your answer forzto two decimal places.

OBSERVED Z=?

CRITICAL VALUE=?

CRITICAL VALUE=?

b. Calculate the p-value for the test.

P-VALUE=?
