In a sample of 24 spools of wire, the average diameter was found to be 3.16mm with a variance of 0.13. give a point estimate for the population standard deviation of the diameter of the spools of wire. round your answer to two decimal places, if necessary.

0.36

Step-by-step explanation:

Given : Sample size of spools of wire : n= 24

The sample variance =

The the sample standard deviation should be the square root of the sample variance.

i.e. Sample standard deviation =

Also, the sample standard deviation(s) is the best estimate of population standard deviation .

Therefore ,  a point estimate for the population standard deviation of the diameter of the spools of wire. =s= 0.36

Hence, a point estimate for the population standard deviation of the diameter of the spools of wire= 0.36

the correct answer is 5 6 and 7

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
