O An oll company purchased an option on land in Alaska, Preliminary geologic studies assigned the following prior probabilities.P(high-quality oil) = 0.45P(medium-quality oil) = 0.20P(no oil) = 0.35a. What is the probability of finding oll (to 2 decimals)?.65b. After 200 feet of drilling on the first well, a soil test is taken, The probabilities of finding the particular type of soil identified by.the test are given below.P(soil|high-quality oil) = 0.25%!P(soil medium-quality oil) = 0.85P(soil no oil) = 0.25Given the soil found in the test, use Bayes' theorem to compute the following revised probabilities (to 4 decimais).P(high-quality oiljsoil)P(medium-quality oil soil)P(no oilsoil)What is the new probability of finding oil (to 4 decimals)?According to the revised probabilities, what is the quality of oil that is most likely to be found?Select your answerO teon Key

Solution: Since we are finding a z-score, we are dealing with the standard normal curve, so the mean is 0 and the standard deviation is 1. Now, to use the MINITAB procedure, we must know the area to the lefty Since the area to the right of the z-score is 0.68, the area to the left is given by 1-0.68 0.32. Input the following to MINITAB: Nd D n Op Out Co Discussion Topics: 1. Copy and paste the inverse cumulative distribution function figure. 2. What is the z-score that has an area of 0.68 to its right?
