PREMISE

For this assignment, you are continuing your role as a new political consultant in (the fictional city of) Central City, Jefferson. Healthcare is of vital importance to every individual and is a very politically important topic. You decide that your candidate, Dr. Geoff Picton, needs to develop a cogent healthcare policy platform, but to help him with that, you decide to spend a week understanding the health concerns of the population of Central City.

QUESTION #1

To start, you are interested in the average age of voters in Central City who voted in the 2020 general election.

Suppose X is a normal random variable, representing voter age, with mean, = 54 years, and standard deviation, s= 11years.

a. Compute the z-value corresponding to X= 37.

b. Suppose the area under the standard normal curve to the left of the z-value found in part(a) is 0.0611. What does that number represent about your population?

c. What is the area under the normal curve to the right of X= 37? What does this number represent?
