A study was conducted of 90 adult male patients following a new treatment for congestive heart failure. One of the variables measured on the patients was the increase in exercise capacity (in minutes) over a 4-week treatment period. The previous treatment regime had produced an average increase of 2 minutes. The researchers wanted to evaluate whether the new treatment had increased the average exercise time compared to the previous treatment. The data yielded a sample average of 2.17 and a standard deviation of 1.05. Sample mean (x) = 2.17 Satandrad Deviation (s) = 1.05 Population mean (M) = 2 Sample size (n) = 90 a) Carryout an appropriate hypothesis test achieve their goal (Use p-value approach). You may use a 5% significance level to draw a conclusion.
