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 252.5 sec. Assume the population standard deviation of song lengths is 53.5 sec....
