A)The scores on an economics examination are normally distributed with a mean of 71 and a standard deviation of 13. If the instructor assigns a grade of A to 13% of the class, what is the lowest score a student may have and still obtain an A?
B)Use the appropriate normal distribution to approximate the
resulting binomial distribution.
A basketball player has a 80% chance of making a free throw.
(Assume that the throws are independent of each other.) What is the
probability of her making 95 or more free throws in 130 trials?
(Round your answer to four decimal places.)
