Answer 1

Answer:

352 students

Step-by-step explanation:

Given

See attachment for table

$n = 400$

Required

Attendance of students in this year's show

First, we calculate the mean of the table

$Mean= \frac{\sum x}{n}$

So, we have:

$Mean= \frac{85\% + 91\% + 92\% + 87\% +84\% + 89\%}{6}$

$Mean= \frac{528\%}{6}$

$Mean= 88\%}$

Multiply the mean by the total students

$Expected = Mean * n$

$Expected = 88\% * 400$

$Expected = 352$
