IQ scores from a normal distribution with µ = 100 and σ = 15. If a random sample is selected from this population, on average, how much distance would you expected between the sample mean and

the population mean for each of the following samples?

a. A sample of n = 9 scores

b. A sample of n = 25 scores

c. A sample of n = 100 scores​

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

you divide them and then you get the answer i took this class this year
