the original claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses A number of years ago, Goku's power level on different days were tabulated. His power level on n - 100 individual days were selected, and his mean power level on those days was x - 7000, and a known standard deviation of s - 500. Use a 0.05 significance level to test the claim that the true mean power level on those days is below 9000.
