A store that sells televisions buys their televisions from a specific manufacturer. The manufacturer claims that only 2% of the televisions they sell have defects, but the manager at the store believes the percentage is actually higher. In the next shipment of 100 televisions, the manager finds that 5 of them are defective. Assume this shipment is a random selection of televisions from the manufacturer. She conducts a hypothesis test where H0: p = 0.02, and HA: p > 0.02 at the alpha = .05 level. She finds the P-value is 0.0162.

Select all that apply.

Select one or more:

a. 0.0162 is the probability of having at least 5 defective televisions in a shipment of 100 given that the true proportion of defective televisions is 0.02.

Since the P-value 0.0162 is less than 0.05, it is significant at that level, so we should reject the null hypothesis in favor of the alternative hypothesis.

b. 0.0162 is the probability that the true proportion of defective televisions is 0.02.

Since the P-value 0.0162 is not higher than 0.05, it is not significant at that level, so we fail to reject the null hypothesis.

c. 0.0162 is the probability of having at least 5 defective televisions in a shipment of 100 given that the true proportion of defective televisions is greater than 0.02.

d. 0.0162 is the probability of having exactly 5 defective televisions in a shipment of 100 given that the true proportion of defective televisions is 0.02.

e. 0.0162 is the probability of having exactly 5 defective televisions in a shipment of 100 given that the true proportion of defective televisions is greater than 0.02.

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.
