Question

For a sample of 38 houses, what would you expect if anything, does she need to assume about the distribution of prices to be able to use the Central Limit Theorem? Are the distribution of he sale prioes to be? A t real state agent has boen assigned 10 houses at random to sell this month She those assumptions easonable whether he mean price of those houses s hypical A. Prices cannot be less than Q, but there is nothing to prevent some O B. Prices tend to increase over time, so the distribution will be skewed to the righ from being espensive, so thay ane lhlto be skeeed to he O C. Prices folow a Poisson O D. Prices tend to be about the same in any given area, so the distrbution is probably uniflorm What assumptions, if any, need to be made to be able to use the Central Limit Theorem? Select all that apply DA. The prices must be assumed to be independent B. The prices must be assumed to be randomly selected. C. The of prices must be assumed to be not too skewed and wthout outlers D. No assumptions are needed Are the assumptions reasonable? Select all that apply DA Risnot reasonable to assume the houses are randomly selected B. It is not reasonable to assume the prices are independert C. Itīs not to assume that there are no outliers D. No assumptions are needed

Answer #1

Answer:

Assumptions about the distribution of the sales price from a sample of 36 houses are given below The distribution of the sales price of house is not skewed. Also, there should not be any outliers in the distribution. Real-estate agent assumptions about the distribution of the sales price from a sample of 10 houses are given below. Since the houses are taken at random, the samples should be independent of each other. The distribution of these houses prices can be expected to be skewed. Also, there can be a chance for an outlier. The shape of the distribution can be checked by constructing a histogram for the data. 1) Price cannot be less than 0, but there is nothing to prevent some from being expensive, so they are likely to be skewed to the right. Option (A) is correct answer 2) No assumptions are needed. Option (D) is correct answer 3) No assumptions are needed Option (D) is correct answer
