Chapter 12.5, Problem 85E
Test Scores Obtain a set of test your instructor.
- a. Determine the mean, median, mode and midrange of the test scores.
- b. Determine the range and standard deviation of the set of scores. (You may round the mean to the nearest tenth when finding the standard deviation.)
- c. Construct a frequency distribution of the set of scores. Select your first class so that there will be between 5 and 12 classes.
- d. Construct a histogram and frequency
polygon of the frequency distribution in part (c). - e. Does the histogram in part (d) appear to represent a
normal distribution ? Explain. - f. Use the procedure explained in Exercise 84 to determine whether the set of scores approximates a normal distribution. Explain.

6. Modelling. Suppose that we have two tanks (A and B) between which a mixture of brine
flows. Tank A contains 200 liters of water in which 50 kilograms of salt has been dissolved
and Tank B contains 100 liters of pure water. Water containing 1kg of salt per liter is
pumped into Tank A at the rate of 5 liters per minute. Brine mixture is pumped into
Tank A from Tank B at the rate of 3 liters per minute and brine mixture is pumped from
Tank A into Tank B at the rate of 8 liters per minute. Brine is drained from Tank B at a
rate of 5 liters per minute.
(a) Draw and carefully label a picture of the situation, including both tanks and the flow
of brine between them.
