Answer:

b. H0: p = 0.65 and HA: p > 0.65

Explanation:

The null hypothesis should be

  • the proportion of women in the real estate profession is 65%

And the alternative hypothesis should be

  • the proportion of women in the real estate profession is higher than 65%

After sample z-statistic and corresponding p-value under the conditions assumed in null hypothesis has to be calculated and compared against %10 significance level p-critical

If the p-value is smaller than p-critical then we can reject the null hypothesis in favor of alternative hypothesis and conclude that the proportion of women in the real estate profession is higher than 65%.
