Return Submit 2 points Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A number of years ago, Goku's power level on different days were tabulated. His power level on n = 243 individual days were selected, and his mean power level on those days was x = 9000, and a known standard deviation of a = 1000. Use a 0.05 significance level to test the claim that the true mean power level on those days is over 9000 (Hin Hypothesis Test for 1 Mean, sigma known). Null Hypothesis, HO Alternative Hypothesis, H1 Test Statistic, z P-value Significance level Conclusion 2 points Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Use either the traditional method or P-value method as indicated. Identify the null and alternative hypotheses, test statistic, critical value(s) or P-value (or range of P-values) as appropriate, and state the final conclusion that addresses the original claim.
