A hypothesis test is performed in which the research (alternative) hypothesis states that more than 15% of a population are unemployed. The p-value for the test is calculated to be 0.018 (with the alpha = 0.05). Which of these statements is correct? A. We reject the null hypothesis and conclude that the research hypothesis is correct: more than 15% of the population are unemployed. B. We reject the null hypothesis and conclude that more than 18% of the population are unemployed. C. We fail to reject the null hypothesis and conclude that exactly 15% of the population are unemployed. D. We fail to reject the null hypothesis and conclude that exactly 85% of the population are unemployed.
A hospital claims that the proportion of full-term babies born in the hospital who weigh less than seven pounds is no more than 44%. Suppose that we want to carry out a hypothesis test for this claim, suspecting otherwise. State the null hypothesis Ho and the alternative hypothesis H, that we would use for this test.

Suppose that in a random selection of 100 colored candies, 26% of them are blue. The candy company claims that the percentage of blue candies is equal to 28%.

After the football team once again lost a game to the college's archrival, the alumni association conducted a survey to see if alumni were in favor of firing the coach. An SRS of 100 alumni from the population of all living alumni was taken. Sixty-four of the alumni in the sample were in favor of firing the coach. Let p represent the proportion of all living alumni who favor firing the coach. The decision made from the above hypothesis test is that: O the observed sample proportion is not statistically significant, and the null hypothesis should be rejected. O the observed sample proportion is statistically significant, and the null hypothesis should be rejected. O the observed sample proportion is statistically significant, and the null hypothesis should not be rejected. O the observed sample proportion is not statistically significant, and the null hypothesis should not be rejected.
Normally only about 19% of people who try to quit smoking succeed, but sellers of a motivational tape claim that listening to their recorded messages can help people quit (i.e., more than 19% of the people who use the tapes will successfully quit). Let p represents the percentage of people who have listened to the recorded messages and have successfully quit. Match the appropriate null and alternative hypotheses, based on the sellers' claim. H,: p = 0.19 p> 0.19 p2 0.19 ps 0.19 p 0.19 p2 0.19 ps 0.19 p < 0.19 Op- 0.19 Do you consider a Type I or Type Il error a more serious mistake here? Why? Your answer should make it clear what Type I and Il errors are in this context.
In a given hypothesis test, the null hypothesis can be rejected at the 0.10 and the 0.05 level of significance, but cannot be rejected at the 0.01 level. The most accurate statement about the ?−p−value for this test is: A. ?-value=0.10p-value=0.10 B. 0.01<?-value<0.050.01<p-value<0.05 C. 0.05<?-value<0.100.05<p-value<0.10 D. ?-value=0.01p-value=0.01
Let p be the propotion of seniors who will play bingo. Based on a random sample of 175 seniors, 103 of them have said that they will play bingo. Using this data, test the null hypothesis that p=.5 versus the alternative that p>.5 at the alpha = .1 level. What is the p-value and conclusion of this test? Should you reject or fail to reject the hypothesis?
