For a data set of the pulse rates for a sample of adult females, the lowest pulse rate is 32 beats per minute, the mean of the listed pulse rates is x overbarequals74.0 beats per minute, and their standard deviation is sequals14.8 beats per minute. a. what is the difference between the pulse rate of 32 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 32 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 32 beats per minute significant?

The difference between the pulse rate of 32 beats per minute and the mean pulse rate of the females 42.

Standard deviations is that [the difference found in part (a), is 2.83.

The pulse rate of 32 beats per minutes to a z score is -3.07.

Given that,

Sample of adult females, the lowest pulse rate is 32 beats per minute,

The mean of the listed pulse rates is x over bar equals74.0 beats per minute,

and their standard deviation is equal 14.8 beats per minute.

According to the question,

       Difference ÷ S = .

If consider pulse rates that convert to z scores between -2 and 2 to be neither significantly low nor significantly high, is the pulse rate of 32 beats per minute significant since z = - 3.07.

The lowest pulse rate is 32 beats per minute

s= 14.8

a) What is the difference between the pulse rate of 32 beats per minute and the mean pulse rate of the females?

= 74- 32

= 42

b) How many standard deviations is that [the difference found in part (a)]

c) Convert the pulse rate of 32 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 32 beats per minute significant?

Since z = - 3.07

Hence pulse rate is significantly low

b
