If the educational level of all united states government employees reveals a mean of 14 years with a standard deviation of 4 years, determine the probability that in a random sample of 50 government employees the average educational level will be between 12 and 16 years. what is the probability that the sample mean will be below 12 years of education?

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.
