Professor Simple Simon designs an experiment to see if college students prefer apple or cherry pie. Prof Simon assigns one group of students to eat apple pie (Xa) and another group to eat chrry pie (Xc).

Prof Simon measured the number of grams of pie each student ate. Given the following results what can Prof Simon conclude?

Apple Pie Data

Xa= 330

X2a = 21100

na = 9

Cherrry Pie Data

Xc= 420

X2c= 24400

nc= 9A)

What is the mean for Xa?

B) What is the mean for Xc?

C) What is the variance for Xa?

D) What is the variance for Xc?

E) What is the t observed (computed)?

F) What is the critical value of t?
