ANSWER THE FOLLOWING PROBLEMS SHOWING COMPLETE SOLUTION ENCLOSE FINAL ANSWER THANK YOU!topic: FUNDAMENTAL SAMPLING DISTRIBUTION Exercise 7.3 Two independent experiments are run in which two different types ofpaint are computed. Eighteen specimens are painted using type A, and drying time(in hours) is recorded each. The same is done with type B. The populationstandard deviations are both known to be 1.0. Assume that the mean drying timeis equal for the two types of paint, find P(Xa – Xg > 1.0), where Xa and Xg areaverage drying times for samples of size na = nR = 18.
