Question

Question 3 (1 point) Hypothesis Test. Gender bias researchers compared the promotion rate of 412 women in manufacturing management positions to the national average which was known to be 75 months for a mostly male population. They measured the number of months each woman worked in middle management before being promoted to senior management, and found an average 79 months (s.d. = 19). Researchers want to know if women are promoted more slowly (i.e. after a larger number of months). Question. Given a 0.01 level of significance, the correct statistical conclusion is to reject the null True False Question 4 (1 point) Hypothesis Test. Gender bias researchers compared the promotion rate of 412 women in manufacturing management positions to the national average which was known to be 75 months for a mostly male population. They measured the number of months each woman worked in middle management before being promoted to senior management, and found an average 79 months (s.d. = 19). Researchers want to know if women are promoted more slowly (i.e. after a larger number of months). Question. What is the correct research conclusion? Choose the best option below. Evidence suggests there is no difference in promotion rates. Evidence suggests a small difference in promotion rates favoring males. Evidence suggests a large difference in promotion rates favoring males. No way to tell.
