A. j. has 20 jobs that she must do in sequence, with the times required to do each of these jobs being independent random variables with mean 50 minutes and standard deviation 10 minutes. m. j. has 20 jobs that he must do in sequence, with the times required to do each of these jobs being independent independent random variables with mean 52 minutes and standard deviation 15 minutes.
(a) find the probability that a. j. finishes in less than 900 minutes.
(b) find the probability that m. j. finishes in less than 900 minutes.

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
