Answer:

Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2). Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).

A local news story claims that 53 of high school males agree with the statement.

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.
