Answer:
The y-intercept is (0, 5).
Step-by-step explanation:
We find the equation of the line in slope-intercept form:
y - y1 = m(x - x1)
y - 13 = 2(x - 4)
y = 2x - 8 + 13
y = 2x + 5 - This is slope-intercept form where the graph passes through the y-axis at y = 5.

Using calculator :
Sample mean = ΣX / n
Sample mean = 5203.23 / 20
Sample mean, m = 260.1615
Sample mean, m = 260.2
Sample standard deviation (s) :
Σ(X - m) / n - 1
= 70.688
= 70.7
((n-1)*s²) / ²0. 975, 19 ; ((n-1)*s²) / ²0.025, 19
95% confidence interval :
(53.787 ; 103.304)
