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
210210
seconds. A simple random sample of
4040
current hit songs results in a mean length of
219.0219.0
sec and a standard deviation of
56.3956.39
sec. Use a
0.050.05
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
210210
sec. What do these results suggest about the advice given in the manual?
State the final conclusion that addresses the original claim. Choose the correct answer below.

What do the results suggest about the advice given in the manual?
A.
The results are inconclusive because the average length of a hit song is constantly changing.
B.The results
suggestsuggest
that the advice of writing a song that must be no longer than
210210
seconds is not sound advice.
C.The results

D.The results suggest that
219.0219.0
seconds is the best song length.
Homework Answers
The statistical software output for this problem is:
Since p - value is greater than 0.05, we do not reject Ho. Hence,
Final conclusion: Option C is correct.
What do the results suggest about the advice given in the manual? Option C is correct.
