The answer is D. Hope that helps!
let x be the age of her son
y = 25 + x
y - 25 = x
(y + 12) + (x + 12) = n
y + x + 24 = n
y + y - 25 + 24 = n
2y - 1 = n
sub
2(38)-1 = n
n = 78
The answer is true they require insurance on all cars
Based on the information given regarding the sampling, the correct option is E. No, because p = 0.53 was one of the most common values in the sampling distribution.
<h3>How to solve the sample.</h3>
From the complete information, it can be deduced that on the dotplot, the center of the sampling distribution is around 0.53. This means that if we construct a confidence interval, there is a high probability that it will have a value of 0.53.
Also, for less than 53% to be true, then most of the dots should have been less than 0.53. In this case, it is centered around 0.53 and so this illustrates that a lot of values are equal to and above 0.53.

I would probably be calm and coaperative with them. I would do this because the more nervous and unsure you act, the more defencive they will most likely be.
I hope this helps :)
