A set of final examination grades in an introductory statistics course is normally distributed, with a mean of 79 and a standard deviation of 9. Complete parts (a) through (d) a. What is the probability that a student scored below 95 on this exam? The probability that a student scored below 95 is 0.9023 (Round to four decimal places as needed.] b. What is the probability that a student scored between 70 and 1017 The probability that a student somed between 70 and 101 is 0 8341 'Round to four decimal places as needed ) c The probabilily is 5%% that a shuland laking the led sumes higher than what grade? he probability is 9%% that a student taking the test scores higher than 91 . (Round to the nearest integer as needed.) d. It the professor grades on a curve (for example, the professor could give A's to the top 10% of the class, regardless of the score], is a student better off with a grade of 88 on the exam with a mean of 79 and a standard deviation of e or a grade of /3 on a different exam, where the main is 65 and the standard deviation is 4? Show your answer statistically and explain A shident is better off with a grade of 80 on the exam with a moan of 79 and a standard deviation of 9 because the 7 value for the grade of BA is and the 7 value for the grade of 73 on the different axiom is|]. (Round to two decimal places as needed.)
