Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternativehypotheses, teststatistic, P-value, and state the final conclusion that addresses the original claim.
In a manual on how to have a number onesong, 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 239.9 sec and a standard deviation of 53.85 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 themanual?
What are thehypotheses?
Identify the test statistic. Rounded 2 decimal places
Identify theP-value. Rounded 3 decimal places
State the final conclusion that addresses the original claim.
What do the results suggest about the advice given in themanual?
