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

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
