Answer:
Step-by-step explanation:
Hello!
What you want to test is if there is a difference between the number of courses taken by students of different years, you can determine 4 populations of students:
Population 1: Freshmen
Population 2: Sophomores
Population 3: Juniors
Population 4: Seniors
To each population you measured the study variable, setting 4 different variables. To compare these variables the best way is to make one test where you compare the four populations at the same time, so the hypothesis is:
H₀: μ₁ = μ₂ = μ₃ = μ₄
H₁: At least one of the population means is different from the others.
The most appropriate test to use to compare the population mean of the 4 groups is an ANOVA.
I hope you have a SUPER day!
