Answer:
The lowest pulse rate is 32 beats per minute
[tex]\bar {x}=74[/tex]
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)]
[tex]= \frac{difference }{s} = \frac{42}{14.8}=2.8378[/tex]
c) Convert the pulse rate of 32 beats per minutes to a z score.
[tex]z=\frac{32-74}{14.8}\\z=-3.07[/tex]
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
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,
- The difference between the pulse rate of 32 beats per minute and the mean pulse rate of the females = 74 - 32 = 42.
- Standard deviations is that [the difference found in part (a),
Difference ÷ S = [tex]\frac{42}{14.8} = 2.837[/tex].
- The pulse rate of 32 beats per minutes to a z score,
[tex]z = \frac{32-74}{14.8} = -3.07[/tex]
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.
