19. A blood pressure testing machine is stationed in a busy corridor in a large shopping mall. For 1 week, a medical student records the diastolic pressure reading of each person who uses the machine between the hours of 10 A.M. and 2 P.M., with the following results: N = 114, ∑ X = 9,561.2, ∑ X2 = 678,360.92. (Statistics for the behavioural Sciences 2014)
a. How many of the sample had scores of 110 or higher?
b. What was the probability of a score of 60 or less?
c. If the normal range for diastolic pressures is between 60 and 90, how many of the 114 persons had a normal reading?
d. Based on these data, what percentage of the population had readings as deviant as 110?
e. What readings were so deviant that less than 5% of the sample had them?
