A university business school is interested in the difference of GPAs across majors. They collect a sample of 7 students from each of 4 different majors: accounting, finance, marketing and analytics. They found that the average GPA was 3.0 for accounting, 3.6 for finance, 3.1 for marketing and 3.5 for analytics. After conducting an ANOVA, the university rejected the null hypothesis. Can they conclude that the GPA of finance students is significantly different from accounting students? Yes No

Answer:

NO

Step-by-step explanation:

Hello!

For this it's been made an ANOVA for four different variables, this means, in the null hypothesis there were four population means tested. When you reject the null hypothesis, you can assume that at least one of the GPA for the four majors is different. To know which one is different, or, if the GPA of finance students is different from the accounting students, you'll have to do an individual test between these two populations.

Hope you have a SUPER day!
