Answer:
a) x = 1.52
b) s = 1.16
Step-by-step explanation:
We have that:
5 students watched 0 movies.
9 students watched 1 movie.
5 students watched 2 movies.
5 students watched 3 movies.
1 student watched 4 movies.
(a) Find the sample mean x.
Sum divided by the number of students. So

(b) Find the approximate sample standard deviation, s.
Standard deviation of the sample.
Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So

8x4x11 - (4x1x3)
352 - 12
= 340
The answer is 340yd^3
Divide both sides by -0.7 to get rid of that pesky thing in the front
0.3x-0.8=6.4
add 0.8 to both sides
0.3x=7.2
divide both sides by 0.3
x=24
