The mean amount of money that a family of four will spend at Kings Island, including the food and souvenirs, is \$130 with a standard deviation of \$12. Assume that this distribution is normal and calculate the following: 1. Find the probability that a particular family of four selected at random spends between \$150 and \$200? 2. What is the probability that the family spends less than \$140? 3. What is the probability that the family spends more than \$170? 4. What is the probability that the family spends between \$130 and \$190? (Be able to draw a graph to illustrate your results.) 5. Find the cost that represents the 50th percentile. 6. Find the cost that represents the 90th percentile. 7. 5% of the families spend below what value? 8. The top 5% of the families spend above what value? 9. Between which two values will the middle 50% of the families spend? 10. What percent of the families spend at least \$120? 11. Use the empirical rule to determine the following: A About 68% of the observations lie between which two values? B About 95% of the observations lie between which two values? C About 99% of the observations lie between which two values? 12. Use the normal distribution to determine the following: A 68% of the observations lie between which two values? B 95% of the observations lie between which two values? C 99% of the observations lie between which two values? Discuss the differences in the results for question 12 and question 11.
