Let's assume the population standard deviation for resting heart rates for a group of students is known to be 12 bpm. A random sample of 25 student heart rates (in bpm) is listed below in the table. At a 0.05 significance level, test the claim that this population of students has a standard deviation equal to 12 bpm. Use this information to answer parts a) - f).
