Researchers gave students enrolled in a section of basic Spanish a set of 50 new vocabulary words to memorize. On Friday the students took a vocabulary test. When they returned to class the following Monday they were retested, without advance warning. Both sets of test scores for the 25 students are shown.
n=12 for both lists.

Friday: 42, 44, 41, 41, 44, 43, 41, 39, 43, 48, 43, 45

Monday: 36, 44, 46, 38, 40, 38, 37, 31, 32, 37, 41, 32

Enter your data into your calculator.
1. Stat, Edit, L1: Friday scores

2. Stat, Edit, L2: Monday scores

3. Display stacked boxplots for the two data sets:

Turn Statplot #1 ON (2nd, y=, Statplot#1), choose the modified boxplot (next to the histogram),
Xlist: L1 (2nd, 1), Freq=1
Turn Statplot #2 ON (Statplot #2, enter), choose the modified boxplot (next to the histogram),
change Xlist: L2 (2nd, 2), Freq=1

4. Zoom 9 to display the stacked boxplots. Remember that Friday data is displayed on top,

Remember: Friday is the top boxplot and Monday is the bottom boxplot.
Compare the two boxplots, noting the location of the quartiles.

Using the quartiles, what percent of the Monday scores were worse than the top 75% of the scores for Friday?
