A company that produces cranberries knows that about 7% of its cranberries are bruised in the baggin process. They changed their bagging method, and they were curious if the proportion of cranberries bruised was different. They tested They tested Ho: p = 0.07 versus Ha: p>0.07 where p is the proportion of cranberries bruised. From a random sample of 600 cranberries they found that 60 were bruised. Those results yielded a test statistic of approximately z = 2.88 and a p-value of 0.004. Assume that the conditions for inference were met. Is there sufficient evidence at the a = 0.01 level to conclude that the proportion of cranberries bruised is different than 7% a Yes, because 10% > 7% Yes, because 0.004 7% ООООО

The authors of a paper compared two different instruments for measuring a person's capacity for breathing out air. (This measurement is helpful in diagnosing various lung disorders.) The two instruments considered were a Wright peak flow meter and a mini-Wright peak flow meter. Seventeen people participated in the study, and for each person air flow was measured once using the Wright meter and once using the mini-Wright meter. The Wright meter is thought to provide a better measure of air flow, but the mini-Wright meter is easier to transport and to use. Use of the mini-Wright meter could be recommended as long as there is not convincing evidence that the mean reading for the mini-Wright meter is different from the mean reading for Wright meter. For purposes of this exercise, you can assume that it is reasonable to consider the 17 people who participated in this study as representative of the population of interest. Data values from this paper are given in the accompanying table.…

Many young men in North America and Europe (but not in Asia) tend to think they need more muscle to be attractive. One study presented 200 young American men with 100 images of men with various levels of muscle. Researchers measure level of muscle in kilograms per square meter (kg/m2) of fat-free body mass. Typical young men have about 20 kg/m2. Each subject chose two images, one that represented his own level of body muscle and one that he thought represented "what 21 women prefer." The mean gap between self-image and "what women prefer" was 2.35 kg/m2. 99 Suppose that the "muscle gap" in the population of all young men has a Normal distribution with standard deviation 2.5 kg/m2. Give a 90% confidence interval for the mean amount of muscle young men think they should add to be attractive to women.
