A study examined the effects of an intervention program to improve the conditions of urban bus drivers. Among other?variables, the researchers monitored diastolic blood pressure of bus drivers in a large city. The?data, in millimeters of mercury?(mm Hg), are based on the blood pressures obtained prior to intervention for the 41 bus drivers in the study. Use technology to complete parts?(a) through?(c) below.

At the 5?% significance?level, do the data provide sufficient evidence to conclude that the mean diastolic blood pressure of bus drivers in this city exceeds the normal diastolic blood pressure of 81 mm?Hg?
