The null and the alternative hypothesis are
vs
The sample proportion is 0.47, with sample size 1500
So the value of the test static is
The test is two tailed test, and the significance level is 0.02,
So critical value is
Also P-value for the test is
Now value of test static is 2.34> 2.326 and P-value is also less than 0.02
So Reject the null hypothesis.
Enough evidence to support the claim that the proportion is not 0.44
