Eact Suppose the probability that a student makes fewer than 8 mistakes on t Use the following information to answer Questions 71 and 72 probability that a student makes from 8 to 12 (inelusive 71) What is the probability a student makes 8 or more of the 27 answers is either right or wroe e exam is 0.26 and that the mistakes is mistakes a) 0.26 b) 0.41 c) 0.67 d) 0.74 72) W hat is the probability a student makes at most 12 mistakes? a) 0.26 b) 0.41 c) 0.67 ) 0.74 73) (G). Assume a woman has 6 children. Assume that babies born are equally likely to be boys (B) or girls none of whom are twins. Which sequence is more h Sequence A: GGGGGG Sequence B: GGBBGG a) The two sequences are equally likely b) Sequence B is more likely c) Sequence A is more likely d) Cannot be determined from information given. 74) This histogram shows the distribution of the nun surveyed in 2012. In this situation, which choice is most likely true? a) The mean is greater than the median. b) The mean and the median are equal. c) The median is greater than the mean 30 d) None of the above 100 Number of Siblin
