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.

Answer:
I’m assuming it’s $13.50 anyway the answer is 20 minutes
Step-by-step explanation:
So subtract $1.50 from 13.50 you are left with $12 then divide that by $0.6 and you should get 20 as your answer
Answer:
B. P′ (−4, 0)
Step-by-step explanation:
You can look at the graph. The X-axis always goes first. SO -4 is first because it's on the x-axis. ANSWER= (-4, 0)
