The members of a rock climbing club can use an indoor rock climbing facility anytime they wish as part of their club membership. As it creates a new budget, the club decides to investigate how often the members use the indoor climbing facility. Then it will decide whether to increase the budget for this facility. Manuel and Gretchen are in charge of gathering this information, so they survey the members of the club. Each person will administer the survey to 15 randomly selected members and record how many days in the past month those members used the indoor facility. Their data is shown in the table.

Step 1) Create a histogram of Gretchen’s data. Use eight bins for your histogram, each bin should be 2 days in width (i. e. 0 to 2 days, 2 to 4 days).

Step 2) Interpret the histogram of Gretchen’s data you created above and fill in the blanks in the following statements. The shape of Gretchen’s data can be described as _. Because of this, the _ would be the best measure of center for this data set. The actual value for the best measure of center is _.

Step 3) Determine the mean, median, and interquartile range for each data set and complete the table below.

Mean ? 9.6
Median 8 ?
IQR 4 ?

Step 4) Remove the outlier from Gretchen’s data set, and recalculate the mean, median, and interquartile range.

Step 5) Which statements are true about Gretchen’s adjusted data set?
A) The data set is approximately symmetric.
B) The data set is skewed left.
C) The center moved closer to the center of Manuel’s data set.
D) The center moved farther from the center of Manuel’s data set.
E) The spread values are farther from the spread values of Manuel’s data set.
F) The spread values are closer to the spread values of Manuel’s data set.
G) The data set is approximately symmetrical.
