A furniture factory makes a 4-piece desk. Quality control at the factory has randomly sampled numerous desk sets and determined the number of damaged pieces in each set.
The table below is a partially completed probability distribution for the random variable X, where X represents
the number of damaged pieces in a randomly selected desk set from this factory.

What is the probability that a randomly selected desk set contains exactly 4 damaged pieces?

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.
