Question

certain group of test subjects had pulse rates with a mean of 81.9 beats per minute and a standard deviation of 12.2 beats per minute. Would it be unusual for one of the test subjects to have a pulse rate of 96.3 beats per minute? Minimum "usual" valueequals nothing beats per minute (Type an integer or a decimal.) Maximum "usual" valueequals nothing beats per minute (Type an integer or a decimal.) Is 96.3 beats per minute an unusual pulse rate? A. Yes comma because it is smaller than the minimum "usual" value. B. No, because it is smaller than the minimum "usual" value. C. No, because it is larger than the maximum "usual" value. D. Yes, because it is between the minimum and maximum "usual" values. E. No comma because it is between the minimum and maximum "usual" values. F. Yes comma because it is larger than the maximum "usual" value.

Answer #1

We know that unusual values are below two standard deviation from the mean and above two standard deviation from the mean.

We have mean = 81.9 beats per minute and standard deviation = 12.2 beats per minute

Range for unusual values are

beats per minute

beats per minute

So, any value less than 57.5 bpm will be considered as unusual and any value above 106.3 bpm will be considered as unusual.

Minimum usual value = 57.5 beats per minute

Maximum usual value = 106.3 beats per minute

It is clear that 96.3 beats per minute is neither less than 57.5 nor more than 106.3. So, 96.3 beats per minute is between the minimum and maximum "usual" values.

Option E is only correct option.

A certain group of test subjects had pulse rates with a mean of
83.6 beats per minute and a standard deviation of 10.4 beats per
minute. Would it be unusual for one of the test subjects to have a
pulse rate of 74.4 beats per minute? Minimum "usual" valueequals
nothing beats per minute (Type an integer or a decimal.) Maximum
"usual" valueequals nothing beats per minute (Type an integer or
a decimal.) Is 74.4 beats per minute an unusual pulse...

A certain group of test subjects had pulse rates with a mean of
73.4 beats per minute and a standard deviation of 12.7 beats per
minute. Would it be unusual for one of the test subjects to have a
pulse rate of 48.8 beats per minute?
Minimum "usual" value=_____beats per minute (Type an integer
or a decimal.)
Maximum "usual" value=_____beats per minute (Type an integer

Is 48.8 beats per minute an unusual pulse rate?

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?

Claim: The mean pulse rate (in beats per minute) of adult
males is equal to 69 bpm. For a random sample of 138 adult males,
the mean pulse rate is 69.9 bpm and the standard deviation is 11.5
bpm. Find the value of the test statistic. The value of the test
statistic is nothing. (Round to two decimal places as
needed.)

The data below shows height (in inches) and pulse rates (in
beats per minute) of a random sample of women. Construct a
scatterplot, find the value of the linear correlation coefficient
r, and find the P-value using α=0.05 Is there sufficient evidence
to conclude that there is a linear correlation between height and
pulse rate?
