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
Answer:
1 ft./yr.
Step-by-step explanation:
When the question asks for rate of growth in a linear equation, we are going to look for slope. Slope formula is (y2-y1)/(x2-x1). We are given the points (2,5) and (5,8).
Now we can plug them into our formula:
(5-8)/(2-5)
-3/-3
1
Therefore, our rate of growth, or slope, is 1.
