Using the given linear function, it is found that the slope is of 73, which means that for each traffic ticket, the cost of car insurance increases by $73.
<h3>What is a linear function?</h3>A linear function is modeled by:
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
In this problem:
- x represents the number of traffic tickets.
- y represents the cost of car insurance.
The function is:
Hence the slope is of 73, which means that for each traffic ticket, the cost of car insurance increases by $73.

Answer:
0.726 < p < 0.874
Step-by-step explanation:
p = 64/83 = about 0.8
confidence interval = p +- z
= 0.8 +- (1.64 x 0.04472)
= 0.8 +- 0.073343
= (0.726656 and 0.873343)
0.726 < p < 0.874
