Homework Answers
1) Variable under study is number of cars sold in given days as
described in question.
2) There are 40 observations for this study.
3) Most commonly used Measure of center are
i) mean ii) median iii) mode
all three are present in the table. Yes, measure of center agree.
4) Since Skewness is 0.59 which is between 0.5 and 1, the
distribution is moderately skewed.
Also given data is positive skewed ( right skewed ).

Describe one or two general observations you can make about
variable X from these results. In particular, discuss how you would
interpret the Kurtosis and Skewness values based on your reading in
Lane or Devore (or any additional web search you might do on those
topics).

The U.S. Department of Energy's Fuel Economy Guide provides fuel efficiency data for cars and trucks. (See exercise 35 on page 77 in your textbook for a similar problem.) Use the data in the FuelData sheet in this workbook to generate excel output to answer the following questions. Please note that units are "liters" for engine size and "miles per gallon" for highway fuel efficiency. Put the output in given space...
