Asimple random sample of 32 men from a normally distributed population results in a standard deviation of 8.8 beats per minute. the normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. if the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. use the sample results with a 0.05 significance level to test the claim that pulse rates of men have a standard deviation equal to 10 beats per minute. complete parts (a) through (d) below.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

answer: 4 (:
