Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, critical value(s), and state the final conclusion that addresses the original claim. In a manual on how to have a number one song, it is stated that a song must be no longer than 210 seconds. A simple random sample of 40 current hit songs results in a mean length of 240.7 sec and a standard deviation of 55.62 sec. Use a 0.05 significance level and the accompanying Minitab display to test the claim that the sample is from a population of songs with a mean greater than 210 sec. What do these results suggest about the advice given in the manual? Complete (a) - (e) a) What are the hypothesis? b) Identify the test statistic. (Round two places) c) Identify the p-value. (Round two places) d) State the final conclusion that addresses the original claim. e) What do the results suggest about the advice given in the manual?
