Answer:
Step-by-step explanation:
Information given
n=370 represent the sample selected
estimated proportion of readers owned a laptop
is the value that we want to test
z would represent the statistic
represent the p value
Creating the hypothesis
We need to conduct a hypothesis in order to test if the true proportion of readers owned a laptop is different from 0.45, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is:
(1)
Replacing we got:
Calculating the p value
We have a bilateral test so then the p value would be:
We first find the shortest distance between the point (2, 0) and the curve 
Let the point on the curve for which the line making the shortest distance be (x, y), then
But,
Therefore,
For minimum d(d)/dx = 0
Therefore, shortest distance is
Since it costs 400 dollars per mile, 4.47 miles will cost 4.47 x 400 = $1,788.20
