2. A class was given two science tests, A and B. Students' scores are summarized in the table below: Scores for test A 30 51 25 43 63 32 39 40 Scores for test B 76 69 50 73 58 48 11 67 Using the information in the table: (a) Construct a back-to-back stem-and-leaf plot (b) Find median for each test (c) Find interquartile range for each test (d) For each test, identify outliers if there is any (e) Display the results in parallel boxplots (f) If the pass score is awarded to the top 50% of the students, what is the minimum pass score in each test?

00:01 Hello students, for the given information of the score of the test a and the score of the test b, we have to construct the back to back stem and the leaf plot.

00:10 Then make two parts here for test a and the test b and center part is for a stem.

00:17 We know that last digit of the number is the our leaf and the remaining part is our stem.

00:34 Then look at the highest maximum values for the test a.

00:41 Minimum value is for test a is 25 and max value is 51 and for test b minimum value is 11 and max value is 76.

00:57 Then we are starting with the stem 1 and end with the 76 because the number minimum value for all this is 11 is the minimum and overall this is 76 is the maximum.

01:11 1, 2, 3, 4, 5, 6, 7.

01:17 Now for the test we construct the leaf part for the test a first.

01:23 Then look at the stem starting with the 1.

01:27 Then there is no number starting with the 1.

01:30 Then look at for the second 2.

01:31 Then 25 then the 2 here is already right then write down here 5.

01:39 Then no 1 then the third for the stem starting with the third point is the 30 and the 32 39.

01:48 Then 2 start first is the 30 then 30 then 32 32 and 39 39.

02:00 Then starting with the 4 is the 43 and 40 then 40 and then 43.

02:10 Then starting with the 5 is only one 51 then the 5 is already here one in the stem part and then starting with the 6 is the 63 then 6 is 3.

02:25 No number in a test a starting with the 7.

02:29 Then now for the leaf part we have to construct the leaf part for the b test part.

02:33 Then starting with the 1 is the only one number 11 then 11.

02:37 Then number starting with the 2 is no number starting with the 3 there is also no number starting with 4 is the 48 then 4 and 8 here.

02:49 Then starting with 5 is a 50 and 58 then 5058.

02:55 5 is already here 0 8.

02:59 Then starting with the 6 is 69 and 67 then 6 7 6 9 and starting with the 7 it's 76 and 73 then 7 3 7 6...
