Information from the american institute of insurance indicates the mean amount of life insurance per household in the united states is $165,000. this distribution follows the normal distribution with a standard deviation of $40,000. if we select a random sample of 50 households, what is the standard error of the mean

$5656.85

Step-by-step explanation:

The standard error of the mean measures the dispersion of sample means about the population mean .

It is also known as the standard deviation of its sampling distribution.

Formula : , where = population standard deviation.

n= sample size.

As per given , we have

sample size : n= 50

Then, the standard error of the mean will be :-

Hence, the standard error of the mean= $5656.85

it will be a cylinder. with a diameter of 8 and 4 single pieces high

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
