5. The average IQ score is 100 points with a standard deviation of 15 points. Uncle Bob says that his IQ is in the 90th percentile. Use this information and a z-table to find Uncle Bob's IQ. Hint: Use the z-table to look up his z-score then solve for his score x in the z-score formula.

6. The average height of men in the US is 177.6 cm

a. How tall is this in inches?

b. If the standard deviation for the heights is 3 inches, and Uncle Bob claims that he is also in the 90^{th} percentile for height, how tall is he? Hint: Use the z-table to look up his z-score then solve for his score x in the z-score formula.

Answer the following by drawing the bell (normal) curve. Label and shade the region desired. You will need to use the z-table from the class session to work the following problems.

8. The life of a 9-volt battery is normally distributed with a mean of μ = 2000 hours and a standard deviation of σ = 40 hours. What is the proportion of batteries with an average life of 2100 hours or more? Draw a normal curve, label the mean and standard deviation, and shade the proportion of batteries with an average life of 2100 hours or more.

9. People spend an average of 7 hours per day on their home computers with a standard deviation of 1 hour. What proportion spends at least 5 hours per day on their home computers? Write a sentence that states your findings.

10. Roadworthy tires last an average of 30,000 miles with a standard deviation of 2500 miles. What proportion of these tires do not last more than 25,000 miles?

11. The average annual consumption of ice cream per capita is μ = 16.5 lbs. in the US. Estimate the total consumption of ice cream in the US. (You may need to look up some information to calculate this). If the standard deviation is σ = 2.5 lbs, what proportion of the US consumes less than 10 lbs. per year?

Total consumption =

Proportion who consume less than 10 lbs. per year =
