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.
