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, 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 234.1 sec and a standard deviation of 54.52 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?
