Douglas took a survey on dill pickles. He was asked questions about what he liked and disliked about dill pickles, when and where he usually ate the pickles, and to list and rate all the brands of dill pickles that he could recall. He was asked his opinion on packaging and on the characteristic taste of the pickles, and what he disliked about all these aspects. The survey was conducted by an ad agency to help develop a creative strategy for dill pickles. If there were several people surveyed besides Douglas, we can assume he was participating in a(n) study.

Let the sample size of leg strengths be 7 and the sample mean and sample standard deviation be 945 watts and 48 watts, respectively. (a) is there evidence that leg strength exceeds 900 watts at significance level 0.05? find the p-value.there is , evidence that the leg strength exceeds 900 watts at ? -0.05. 0.001 < p-value 0.005 0.05 p-value < 0.10 0.10 p-value < 0.25 o 0.010 p-value 0.025 (b) compute the power of the test if the true strength is 915 watts. (c) what sample size would be required to detect a true mean of 915 watts if the power of the test should be at least 0.9? n= exact number, no tolerance
