The data below represents the overall miles per gallon (MPG) of 2008 SUVs priced under $30,000. Complete parts a and b below. 21,19,20,21,20,17,18,16,19,20,17, D 18,21,17,16,19,17,18,16,19,15, 24 a. Construct a 90% condence interval estimate for the population mean miles per gallon of 2008 SUVs priced under $30,000, assuming a normal distribution. D 5 us D (Round to two decimal places as needed.) b. Interpret the interval constructed in (a). Choose the correct answer below. 0 A. With 90% condence, the mean miles per gallon in the population of 2008 SUVs is the sample mean. 0 B. With 90% condence, the mean miles per gallon in the population of 2008 SUVs is somewhere in the interval. 0 C. With 90% condence, the mean miles per gallon in the sample of 2008 SUVs is somewhere in the interval. 0 D. With 90% condence, the mean miles per gallon in the sample of 2008 SUVs is the population mean
