Suppose that a drug test for an illegal drug is such that it is 98% accurate in the case of a
user of that drug (e. g. it produces a positive result with probability .98 in the case that the tested
individual uses the drug) and 90% accurate in the case of a non-user of the drig (e. g. it is negative
with probability .9 in the case the person does not use the drug). Suppose it is known that 10% of
the entire population uses this drug.
You test someone and the test is positive. What is the probability that the tested individual
uses this illegal drug?
What is the probability of a false positive with this test (e. g. the probability of obtaining a positive drug test given the person tested is a non-user)?
What is the probability of obtaining a false neg

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.
