In an effort to reduce the number of hospital-acquired conditions (such as infection resulting from the hospital stay), Medicare officials score hospitals on a 10-point scale with a lower score representing a better patient track record. The federal government reduces Medicare payments to those hospitals with the worst scores. The following data represent the scores received by Illinois hospitals. Score 1-1.9 2-2.9 3-3.9 4-4.9 5-5.9 6-6.9 7-7.9 8-8.9 9-10 Total Frequency 3 12 16 23 23 21 17 5 5 125 a) Determine the probability that a randomly selected hospital in Illinois has a score between 7 and 7.9. b) Determine the probability that a randomly selected hospital in Illinois has a score that is not between 7 and 7.9. c) Determine the probability that a randomly selected hospital in Illinois has a score less than 5.
