The highway mileage (mpg) for a sample of 8 different models of
a car company can be found below. Which boxplot would be most
appropriate? 18, 20, 24, 26, 30, 32, 36, 36
Homework Answers
"C" is the answer.
A boxplot is a standardized way of displaying the distribution of data based on a five number summary (“minimum”, first quartile (Q1), median, third quartile (Q3), and “maximum”).
So, there are 8 observation this data will have two medians that are 26 and 30. So the median of this data will be the average of these two and that comes out to be 28. The vertical line in the box of the box plot represents the median value of the data. So the answer will be C.

Ford claims that its Spiffy Sedan averages 31 mpg on the highway. Harold believes that Ford is exaggerating and the Spiffy in fact averages less than 31 mpg. Harold randomly selects 8 Super Spiffys from local car dealerships and tests their gas mileage on the highway. He finds the following mpg scores: Calculate the mean and standard deviation of the sample data, and then test Harold’s claim at the 0.05 level of significance. Ford claims that its Spiffy Sedan averages...
