so the rectangular prism, or that box, is really just 6 rectangles stacked up to each other at the edges, notice
front and back are just two 9x5 rectangles
left and right are just two 5x4 rectangles
top and bottom are just two 9x4 rectangles
get the area of all 6, sum them up, and that's the area of the box.

Answer:
The test statistic for Business College is -0.9944
The test statistic for Liberal Arts College is 1.1483
The test statistic for Education College is 0
Step-by-step explanation:
The percentage of ABC University college students in
Business College = 35%
Liberal Arts College = 35%
Education College = 30%
The number of students in the sample = 300 students
In the sample, the number of students in;
Business College = 90
Liberal Arts College = 120
Education College = 90
Therefore;
The percentage of Business College students = 90/300 × 100 = 30%
The percentage of Liberal Arts College, = 120/300 × 100 = 40%
The percentage of Education College, = 90/300 × 100 = 30%
The test statistic for the difference in two proportions is given as follows;
Where;
= The sample proportion
p = The population proportion
q = 1 - p
n = The sample size
The test statistic for Business College is;
The test statistic for Liberal Arts College is;
The test statistic for Education College is;
