Question

For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 36 beats per minute, the mean of the listed pulse rates is x overbarequals74.0 beats per minute, and their standard deviation is sequals21.3 beats per minute. a. What is the difference between the pulse rate of 36 beats per minute and the mean pulse rate of the females? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the pulse rate of 36 beats per minutes to a z score. d. If we consider pulse rates that convert to z scores between minus2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 36 beats per minute significant?

Answer #1

Assume that an adult female is randomly selected. Suppose
females have pulse rates that are normally distributed with a mean
of 74.0 beats per minute and a standard deviation of 12.5 beats per
minute. Find the probability of a pulse rate between 61 beats per
minute and 70 beats per minute.

Assume that an adult female is randomly selected. Suppose
females have pulse rates that are normally distributed with a mean
of
71.071.0
beats per minute and a standard deviation of
12.512.5
beats per minute. Find the probability of a pulse rate
between
5757
beats per minute and
6767
beats per minute. (Hint: Draw a graph.)
The probability is....
