For 30 recent Academy Award ceremonies, ages of Best Supporting Actors (x) and ages of Best Supporting Actresses (y) are recorded. The 30 paired ages yield x = 52.1 years, y = 37.3 years, r = 0.076, P-value = 0.691, and yn = 34.4 + 0.0547x.   Find the best predicted value of yn (age of Best Supporting Actress) in 1982, when the age of the Best Supporting Actor (x) was 46 years.  Use a significance level of 0.05   A. Should this model be used for making predictions? Why or why not? B. Calculate the best predicted value of the age of the Best Supporting actress in 1982.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
