The following data represent the repair cost for a low-impact collision in a simple random sample of small to midsize SUVs (such as the Honda CRV or Toyota RAV4).

$3148 $2758 $1071 $3345 $743 $2057 $1663 $2637 $773 $1300

Question #1:Is it reasonable to conclude the data come from a population that is normally distributed? Include any and all information you used to make your decision. Then, address what else you would need to know before constructing a confidence interval for the mean cost of repair.

Question #2:Construct and interpret a 95% confidence interval for the population mean cost of repair.

Question #3:Suppose you obtain a simple random sample of 10 Honda CRVs that were in a low-impact collision and determine the cost of repair. Do you think a 95% confidence interval would be wider or narrower? Explain.
