Problem-Solving Applications: Mixed Review

9-16

Solve each problem and explain the method you used.

0 1. In their last 8 basketball games, the Johnston Jump Shots

score these points: 85, 62, 74, 71, 81, 65, 81, and 57.

Find the mean, median, mode, and range. Which

measure gives the most useful information about how well

the Johnston Jump Shots can shoot? Explain.

0 2. Make a line plot for this data set: 33, 43, 47, 44, 42, 46,

and 46. Identify any clusters, gaps, and outliers and then

explain how the outlier affects the mean in this data set.

0 3. Make a box-and-whisker plot for this data set: 11, 14, 15,

11, 2, 3, 5, 2, 7, 6, 3, 10, and 9. Find the extremes,

the median, and the lower and upper quartiles.

0 4. If three fifths of 50 students in a random survey said

basketball is their favorite sport, predict how many of

350 students do notfavor basketball.

Use the stem-and-leaf plot for problems 5–7.

0 5. Find the mean, median, mode, and range

of the Victors’ scores.

0 6. If the Victors won each game in which their score

was higher than the mean of all of their scores,

how many games did they win?

0 7. Last season, the Victors scored a total of 24 less

points in the same number of games. What was

their mean score last season?

Use the line graph for problems 8– 10.

0 8. Which team had the greater mean score

in February?

0 9. Which team had a mean score of 62

in March?

10. Over the four months, which team
    had the greater mean score?
