Which of the following would produce a standard error of 2 points? n = 5 scores from a population with σ = 20 n = 5 scores from a population with σ = 80 n = 100 scores from a population with σ = 20 n = 100 scores from a population with σ = 40

n = 100 scores from a population with σ = 20

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, of

n = 5 scores from a population with σ = 20

n = 5 scores from a population with σ = 80

n = 100 scores from a population with σ = 20

.

This one is the correct answer.

n = 100 scores from a population with σ = 40

.

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
