Using the Central Limit Theorem, it is found that the standard deviation is of 0.0971.
<h3>What does the Central Limit Theorem states?</h3>- It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean
and standard deviation
, as long as
and
.
- It also states that when two variables are subtracted, the standard deviation is the square root of the sum of the variances.
In this problem, for each sample, the standard error is given by:
Hence, for the distribution of differences, it is given by:

rate of change is the slope
slope = (y2-y1)/(x2-x1)
m= (180-120)/(3-2)
m = 60/1
m = 60
b. point slope form
y-y1 = m(x-x1)
y-120 = 60 (x-2)
c see attached graph. x>=0 since it is hours
d the y intercept is
y -120 = 60x-120
add 120 to each side
y = 60x
