A set of final examination grades in an introductory statistics course is normally distributed, with a mean of 72 and a standard deviation of 9. What is the probability that a student scored between 63 and 97?

Scores on an examination are assumed to be normally distributed with mean 78 and variance 36 a. What is the probability that a person taking the examination scores higher than $72 ?$ b. Suppose that students scoring in the top $10 \%$ of this distribution are to receive an A grade. What is the minimum score a student must achieve to earn an A grade? c. What must be the cutoff point for passing the examination if the examiner wants only the top $28.1 \%$ of all scores to be passing? d. Approximately what proportion of students have scores 5 or more points above the score that cuts off the lowest $25 \% ?$ e. Answer parts $(\mathrm{a}),(\mathrm{b}),(\mathrm{c}),$ and $(\mathrm{d}),$ using the applet Normal Tail Areas and Quantiles. f. If it is known that a student's score exceeds $72,$ what is the probability that his or her score exceeds 84?
