As a result of government and consumer pressure, automobile manufacturers in the United States are deeply involved in research to improve their products' gasoline mileage. The table below shows the data on the mileage (rounded to the nearest mile for convenience) obtained by test versions of a compact model designed to achieve 40
mpg: 35, 36, 37, 38, 39. 40, 41, 42, 43, 44, 45
freq: 30, 41, 29, 32, 43, 50, 42, 36, 29, 19, 18
What is the mean fuel efficiency of these test versions in kilometers per liter? Assume 1 mile = 1.61 kilometer and 1 gallon = 3.785 liters.

About 80% of professional baseball players earn less than the average salary of professional baseball players. The distribution of salary of professional baseball players is
| a. |
mostly symmetric |
|
| b. |
somewhat skewed to the right |
|
| c. |
substantially skewed to the right |
|
| d. |
somewhat skewed to the left |
|
| e. |
substantially skewed to the left |
Given that around 80% of professional baseball players earn less than the average salary of professional baseball players which indicates that there are some outliers at right tail which is making the mean high. Hence,
The distribution will be substaintially skewed to the right.
Option C is correct.
