Step 1:
Ho: p = 0.74
Ha: p
0.74
Step 2: test statistics
n = 500
x = 360
z = -1.020
p value = 2 * P( Z < - 1.020) = 2 * 0.1539 = 0.3078
Step 3:
alpha = 0.05
The z-critical values for a two-tailed test, for a significance level of α=0.05
zc = −1.96 and zc = 1.96
As the z stat does not fall in the rejection region, we fail to reject the Null hypothesis.
Also as the p value is greater than alpha (0.05) , we fail to reject the Null hypothesis.
