Question 59, 7.8.361 HW Score: 23.91%, 14.11 of 59 points Save Homework: CH 7 Normal Distribution Part 1 of 3 O Points: 0 of 1 In sports betting, sports books establish winning margins for a team that is favored to win a game. An individual can place a wager on the game and will win if the team bet upon wins after accounting for this spread. For example, if Team A is favored by 5 points, and wins the game by 7 points, then a bet on Team A is a winning bet. However, if Team A wins the game by only 3 points, then a bet on Team A is a losing bet. Suppose that in games, the margin of victory for the favored team relative to the spread is approximately normally distributed with a mean of 0 points and a standard deviation of 11.3 points. Complete parts a through c below. (a) What is the probability that the favored team wins by 6 or more points relative to the spread? The probability is (Round to four decimal places as needed.)

With this information, answer the following questions. (a) What proportion of light bulbs will last more than 62 hours? (b) What proportion of light bulbs will last 53 hours or less? (c) What proportion of light bulbs will last between 57 and 62 hours? (d) What is the probability that a randomly selected light bulb lasts less than 45 hours?

Suppose that the incubation times are approximately normally distributed with a standard deviation of 1 day. (a) What is the probability that a randomly selected fertilized egg hatches in less than 19 days? (b) What is the probability that a randomly selected fertilized egg takes over 21 days to hatch? (c) What is the probability that a randomly selected fertilized egg hatches between 18 and 20 days? (d) Would it be unusual for an egg to hatch in less than 17 days? Why?

Assuming drive-through times are normally distributed with o = 2.9 seconds, complete parts (a) through (d) below. (a) What is the probability that a randomly selected car will get through the drive-through in less than 61.5 seconds? The probability is . (Round to four decimal places as needed.)
