Hello!
You have one population: Students at ABC University
One study variable: X: College a student is enrolled in, categorized: Bussiness College "B", Liberal Arts College "A" and Education College "E".
The objective of this study is to test if the proportions of students enrolled in each college are different from the known data.
To do this a sample of 300 students was taken and the major they are studying recorded, the observed proportions are to be compared to the expected proportions.
The correct statistic test to use in this case is a Chi-Square Goodness to Fit test.
I hope it helps!
To add or subtract fractions, you need to make them have the same denominator, either by multiplying or dividing the numerator and denominator of the fraction by the same number.
3/4=9/12(multiply 3)
1/6=2/12(multiply 2)
9/12-2/12=7/12
Hence,
3/4-1/6=7/12
Hope this helps you to understand. :)
