Alarge insurance company wanted to estimate u, the mean claim size (in 5) on an auto insurance policy. a random sample of 225 claims was chosen and it was found that the average claim size was $2875. from past experience the population standard deviation is assumed to be $1350.
which of the following is the point estimate for u?

a. $225
b. $2875
c. $1350
d. none of the above.

B. $2875

Step-by-step explanation:

We know that best point estimate of population mean is the sample mean.

Given : A large insurance company wanted to estimate , the mean claim size (in 5) on an auto insurance policy.

A random sample of 225 claims was chosen and it was found that the average claim size was $2875.

i.e. Sample mean

That means , the point estimate for

Hence , the correct answer is option B . $2875.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
