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?

Answer:

The lowest pulse rate is 32 beats per​ minute

\bar {x}=74

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)]

= \frac{difference }{s} = \frac{42}{14.8}=2.8378

c) Convert the pulse rate of 32 beats per minutes to a z score.

z=\frac{32-74}{14.8}\\z=-3.07

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

anygoal [31]

Answer:

1. 700

2. $157.50

3. $857.50

Step-by-step explanation:

Regular pay is calculated by taking 40 hours x $17.50 to get $700.

Overtime is calculated by taking 6 hours x 17.50 x 1.50 to get $157.50

Gross pay would be adding these two amounts together.
