Question

refer to the accompanying boxplots that are drawn on the same scale. the top boxplot represents weights (kg) of a sample of male u.s. army personnel in 1993, and the bottom boxplot represents weights (kg) of a sample of male u.s. army personnel in 2018. what story is told by these boxplots? click the icon to view the boxplots. choose the correct answer below. a. it appears that weights of u.s. army males did not change from 1993 to 2018. b. it appears that weights of u.s. army males increased from 1993 to 2018. c. it appears that weights of u.s. army males decreased from 1993 to 2018. d. it appears that weights of u.s. army males both increased and decreased from 1993 to 2018.

Explanation:

Box - plots show the distribution of data. If the box - plot for 2018 is shifted to the right compared to 1993, it indicates an increase in the values (weights in this case). Without seeing the actual box - plots, generally, if the median, quartiles, and overall spread of the 2018 box - plot are at higher values than the 1993 box - plot, it means weights increased.

Answer:

B. It appears that weights of U.S. Army males increased from 1993 to 2018.
