Answer:
352 students
Step-by-step explanation:
Given
See attachment for table
[tex]n = 400[/tex]
Required
Attendance of students in this year's show
First, we calculate the mean of the table
[tex]Mean= \frac{\sum x}{n}[/tex]
So, we have:
[tex]Mean= \frac{85\% + 91\% + 92\% + 87\% +84\% + 89\%}{6}[/tex]
[tex]Mean= \frac{528\%}{6}[/tex]
[tex]Mean= 88\%}[/tex]
Multiply the mean by the total students
[tex]Expected = Mean * n[/tex]
[tex]Expected = 88\% * 400[/tex]
[tex]Expected = 352[/tex]
