z=3.8196
Step-by-step explanation:
-We notice that this is a normal distribution problem.
-Given the mean is $8500, standard deviation is $1200 , and n=350, the critical z-value using alpha=0.05 is calculated as:

Hence, the test statitic is z=3.8196
If s represents the number of students, then the number of pizzas is
s/4 + 2 = 9
s/4 = 7 . . . . . . subtract 2
s = 28 . . . . . . multiply by 4
There are 28 students.
