When 328 college students are randomly selected and surveyed, it is found that 122 own a car. find a 99% confidence interval for the true proportion of all college students who own a car?

Step-by-step explanation:

We know that,

where

r = number of successful trials = 122,

n = 328

p = proportion

From probability distribution we also know that,

for a 99% confidence level = 2.576

Marginal error will be,

Putting the values,

So the interval will be,

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
