For a test of Ho: p = 0.5, the z test statistic equals 1.52. Find the p-value for Ha: p > 0.5.
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to your Z score.

To find the p-value for Ha: p > 0.5, we need to calculate the area under the standard normal curve to the right of the observed z-test statistic of 1.52.
Here are the steps to calculate the p-value:
1. Determine the area to the left of the observed z-test statistic. Since we want to find the area to the right, we subtract the area to the left from 1.
Left area = 1 - (area to the left)
2. Look up the area to the left of the observed z-test statistic using a standard normal distribution table or a calculator.
The area to the left of 1.52 is approximately 0.9357.
3. Calculate the p-value by subtracting the left area from 1:
p-value = 1 - 0.9357
= 0.0643
Therefore, the p-value for Ha: p > 0.5 is approximately 0.0643.
