Answer:
99% Confidence interval: (50.9,61.3)
Step-by-step explanation:
We are given the following in the question:
Sample mean, 
= 56.1
Sample size, n = 72
Alpha, α = 0.01
Sample standard deviation, σ = 16.7
Degree of freedom = n - 1 = 71
99% Confidence interval:
Putting the values, we get,
(-4,-4)(1,3)
slope = (3 - (-4) / (1 - (-4)
slope = (3 + 4) / (1 + 4) = 7/5
y - y1 = m(x - x1)...using (-4,-4)
slope(m) = 7/5
y - (-4) = 7/5(x - (-4) =
y + 4 = 7/5(x + 4) <==here is one
y - y1 = m(x - x1)..using (1,3)
slope = 7/5
y - 3 = 7/5(x - 1) <== here is the other one
