My dad if this doesn’t help
Answer:
(A) Mean = $24,500, Standard deviation = 12,875/ √40
Explanation:
Because the sample size is large (n = 40 > 30) the sampling distribution of the sample mean sales price is approximately normal. The mean is
μx =μ=24,500 and the standard deviation is the standard deviation divided the square root of n
I would say about 10+. It really just depends on if you are planning on writing a long book, or a short book, but in my opinion, it would be 10+.
It's showing that the center divider will end. So, option B as correct.
