Question

question 24, *3.2.34 part 1 of 3 body and exam measurements were collected from 300 subjects. the pulse rates from 100 males have a mean of 68.7 beats per minute and a standard deviation of 10.8 beats per minute. use the range - rule of thumb for identifying significant values to identify the limits separating values that are significantly low or significantly high. is a pulse rate of 70.0 beats per minute significantly low, significantly high, or neither? (all of these pulse rates are measured at rest.) explain. click the icon to view the male pulse rates. significantly low values are beats per minute or lower. (type an integer or a decimal. do not round.)

Explanation:

Step1: Recall range - rule - of - thumb for significant low values

Significantly low values are $\mu - 2\sigma$ (where $\mu$ is the mean and $\sigma$ is the standard deviation).

Step2: Identify given values

We are given $\mu = 68.7$ and $\sigma=10.8$.

Step3: Calculate significantly low value

$68.7-2\times10.8=68.7 - 21.6=47.1$

Answer:

$47.1$
