Which of the following statements is not true? a) The standard deviation of the sampling distribution of sample mean = σ/√n b) T
I am Lyosha [343]

Answer:

e) The mean of the sampling distribution of sample mean is always the same as that of X, the distribution from which the sample is taken.

Step-by-step explanation:

The central limit theorem states that

"Given a population with a finite mean μ and a finite non-zero variance σ2, the sampling distribution of the mean approaches a normal distribution with a mean of μ and a variance of σ2/N as N, the sample size, increases."

This means that as the sample size increases, the sample mean of the sampling distribution of means approaches the population mean.  This does not state that the sample mean will always be the same as the population mean.

Natali [406]
Let x = the number of green apples, let 4x = the number of red apples
4x + x = 50         Set up the quation
5x = 50               Combine like terms
----   ----               Divide by 5 on both sides to get x alone
5      5
x = 10 green apples
4x = 4(10) = 40 red apples
