Statistics

  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, μ = 54 years, and standard deviation, s = 11 years.


  2. 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?
