The Baltimore Ravens won the American football championship in 2013. In the same season, the Kansas City Chiefs had a record of 2 wins and 14 losses.

The dot plots below show the 40-yard dash times (in seconds) of the defensive backs on each team's roster. Defensive backs mainly defend against passes, and the 40-yard dash is the main measure of speed used in American football.

Which pieces of information can be gathered from these dot plots? (Remember that lower 40-yard dash times are faster.)

Choose all answers that apply:
A)The defensive backs on the Chiefs are faster on average.
B) The speed of the defensive backs on the Chiefs varies noticeably more than the speed of the defensive backs on the Ravens.
C) None of the above

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
