Question

A certain group of test subjects had pulse rates with a mean of 83.4 beats per minute and a standard deviation of 11.5 beats per minute. Use the range rule of thumb to identify the limits separating values that are significantly low or significantly high. Is a pulse rate of 56.4 beats per minute significantly low or significantly high?

Answer #1

Given that,

mean = 83.4 beats per minute and

standard deviation = 11.5 beats per minute

z-score for the score of x = 56.4 beats per minute

since, z-score = -2.35 is less than -2, we can say that, pulse
rate of 56.4 beats per minute is **significantly
low.**

**Note:** if the z-score of a value is less than -2
then this value is significantly low and if the z-score is greater
than 2 then this value is significantly high.

A certain group of test subjects had pulse rates with a mean
of
78.778.7
beats per minute and a standard deviation of
11.911.9
beats per minute. Use the range rule of thumb to identify the
limits separating values that are significantly low or
significantly high. Is a pulse rate of
142.5142.5
beats per minute significantly low or significantly high?
Significantly low values are
nothing
beats per minute or lower.

cm and a standard deviation of 1.39
cm. Use the range rule of thumb to identify the limits
separating values that are significantly low or significantly
high.

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)]?...

Suppose the mean pulse rate of college students is 68 beats per
minute with a standard deviation of 11.5. You conduct a special
exercise program for 37 college students. After completing the
program, the mean pulse rate of the students was 64.4. Test the
hypothesis that the program lowered students’ pulse rates using a =
0.01.
