7) Reading Rates. The reading speed of sixth-grade students is approximately normal, with a mean speed of 125 words per minute and a standard deviation of 24 words per minute. a) Label the normal curve below with the appropriate parameters describing the reading speed of sixth-grade students. In parts b-e use, describe each probability using the appropriate notation. b) Find and interpret the probability that a randomly selected sixth-grade student reads less than 100 words per minute. c) Find and interpret the probability that a randomly selected sixth-grade student reads more than 140 words per minute. d) Find and interpret the probability that a randomly selected sixth-grade student reads between 110 and 130 words per minute. e) Would it be unusual for a sixth grader to read more than 200 words per minute. if they cannot both occur. 5) If events A and B are disjoint, P (E or F) = 6) If two events are not disjoint, P (E or F) = 7) What is the multiplica 4| Page
