A simple random sample of 40 current hit songs results in a mean length of 235.6 sec and a standard deviation of 56.82 sec. Use a 0.05 significance level to test the claim that the sample is from a population of songs with a mean greater than 210 sec. 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. What are the hypotheses? O A. Ho: H=210 sec O B.
