Consider a sample of blades for a circular saw. Their diameters are measured and found to have a variance of 2.42. Give a point estimate for the population variance in diameters of blades for a circular saw. Round your answer to two decimal places, if necessary.

2.42

Step-by-step explanation:

We are asked to consider a sample of blades for a circular saw, and their diameters were measured.

We are told they have a sample of variance, S²= 2.42

We are told to give a point estimate for the population variance in diameters of blades for the circular saw.

The sample variance, S² can be said to be a point estimate of the population variance.

Therefore, it can be said that the sample variance, S² is a point estimate for the population variance, b².

Which can also be written as:

b² = S²

b² = S² = 2.42

• The point estimate for the population variance is 2.42

8 2/3 is the answer

step-by-step explanation: just use a calculator

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
