A company is criticized because only 14 of 42 executives at a local branch are women. The company explains that although this proportion is lower than it might wish, it's not a surprising value given that only 40% of all its employees are women. The company has more than 500 executives worldwide. Test an appropriate hypothesis and state the conclusion. A) Determine the hypotheses for this test. (The proportion of female executives in the entire company is denoted by p.) B) Calculate the test statistic. z= (Round to two decimal places as needed.) Part 3 Find the P-value. P-value= (Round to three decimal places as needed.) Part 4 State the conclusion of the test. Choose the correct answer below. A. Because the P-value is low, fail to reject H0. These data show that the proportion of women executives in the company is less than the 40% of women in the company in general. B. Because the P-value is low, reject H0. These data show that the proportion of women executives in the company is less than the 40% of women in the company in general. C. Because the P-value is high, reject H0. These data do not show that the proportion of women executives in the company is less than the 40% of women in the company in general. D.Because the P-value is high, fail to reject H0. These data do not show that the proportion of women executives in the company is less than the 40% of women in the company in general.
