Question

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 233.6 sec and a standard deviation of 53.25 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?

Answer #1

as p value is less than 0.05 level we reject null hypothesis

we can conclude that manual advice of having song length less than 210 second is incorrect.

Test the following claim. Identify the null hypothesis,
alternative hypothesis, test statistic, critical value(s),
conclusion about the null hypothesis, and final conclusion that
addresses the original claim. A manual states that in order to be
a hit, a song must be no longer than three minutes and thirty
seconds (or 210 seconds). A simple random sample of 50 current
hit songs results in a mean length of 250.0 sec. Assume the
population standard deviation of song lengths is 54.5 sec....
