Question

The dot plot shows a random sample of number of miles completed in a session by two different running clubs. Compare the mean values of the dot plots. Round to the nearest tenth. Which makes a comparative inference about the runners in both clubs?

(A) There is about the same variation in the number of miles run by each member in both clubs.
(B) There is less variation in the number of miles run by the members of Club Fit than by the members of Club Agile.
(C) There is less variation in the number of miles run by the members of Club Agile than by the members of Club Fit.

Answer 1

Without the provided dot plots, we cannot compare the mean values or variations between the two running clubs. Once the dot plots are available, the mean can be calculated and the variations analyzed to make an accurate comparison and inference.

Step-by-step explanation:

To compare the mean values of the dot plots for the two running clubs, we would need to calculate the mean (average) number of miles completed by each club. The mean is found by adding all the values together and then dividing by the number of values. However, the actual dot plots are not provided in your question, so we cannot perform this calculation or make a definitive comparison of the means. If provided with the dot plots, we could also determine which statement is accurate regarding the variation of miles run by each club's members.

Regarding the examples given for concepts in statistics, they illustrate the different ways data can be analyzed. For instance, dot plots and box plots can provide insights into the shape of the distribution, variation, and central tendency (mean and median) of a data set. These tools are essential in making comparative inferences about different populations or samples.
