Test the claim that for the population of statistics final exams, the mean score is 79 using alternative hypothesis that the mean score is different from 79. Sample statistics include ?=17, x¯=80, and ?=16.s=16. Use a significance level of ?=0.01.. (Assume normally distributed population.)The test statistic is
Wheaties cereal is claimed to have an average of 3 grams of dietary fiber per serving. We want to test this hypothesis and to see whether we believe that is true or that the mean amount of fiber is significantly different from 3 grams. A random sample of 25 servings was taken and it yielded a sample mean of 3.4 grams with the sample standard deviation in the amount of fiber, s = .8 grams. %3D Assume that software has determined the p-value to be.02. Carry out the test at the 5% level of significance. Be sure to state your decision rule and your decision for the test.
