Health professionals are often concerned about our lifestyles and how they affect our well being. A group of medical researchers knew from previous studies that in the past, about 39% of all men between the ages of 45 and 59 were regularly active. Because regular activity is good for our health, researchers were concerned that this percentage had declined over time. For this reason, they selected a random sample, without replacement of 1977 men in this age group and interviewed them. Out of this sample, 680 said that they were regularly active (Elwooxl et al. 2013).

QUESTION: Carry out a hypothesis test that will test whether the proportion of regularly active men in this age group has declined. Use a significance level of 5%.
