In order to achieve maximum results from aerobic exercise, one’s heart rate at a certain level. a 35-yr-old woman with a resting heart rate of 80 beats per minute should keep her heart rate between 143 and 164 beats per minute while exercising. she check her pulse for 10 sec while exercising. what should the number of beats be ?

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
