Use the Following Information to Answer the Question

Short Answer

Use the following information to answer the question. Suppose the manager of a large appliance and electronics store wants to estimate the amount spent by customers during the holiday season. He took a random sample of customers and recorded the amount they spent. A histogram of the data shows that the data is strongly left- skewed. The figures below show the confidence intervals for the mean amount spent using (A)raw (untransformed)data, and (B)log- transformed data, which showed a more normally distributed data set.

-Calculate the width of both intervals (note that you will need to convert the
log- transformed interval back into dollars)and state which interval is narrower?
