Two data sets are given below, each representing times (in minutes) to complete a given task for two different samples of students.

Data Set A: 3.1, 4.7, 7.3, 8.1, 8.1, 8.7, 8.8, 9.1, 9.1, 9.2

Data Set B: 5.2, 5.6, 5.8, 6.9, 7.0, 7.7, 7.9, 8.5, 8.8, 12.5

Complete the back-to-back stem plot for data set B by adding the numbers that belong in each class below, using a class width of 1. Do not enter spaces between the numbers. If a class does not contain anything, then write the word "empty". Key: 3|1 = 3.1 minutes

5 |__________________________(Blank #1)

6 |__________________________(Blank #2)

7 |__________________________(Blank #3)

8 |__________________________(Blank #4)

9 |__________________________(Blank #5)

10|__________________________(Blank #6)

11|__________________________(Blank #7)

12|__________________________(Blank #8)

Blank #9: For both data sets, the mean is approximately 7.6 minutes and the standard deviation is approximately 2.0 minutes. The mean and standard deviation are not the best to use in comparing centers and spreads of these distributions because they are ______________ in shape.

Blank #10: Find the median and IQR for data set A, rounding to one decimal place if needed. Report your answer as median,IQR with no extra spaces or units.

Blank #11: Find the median and IQR for data set B, rounding to one decimal place if needed. Report your answer as median,IQR with no extra spaces or units.

Question 2 options:
