Question
Five pulse rates are randomly selected from a set of measurements. The five pulse rates have a mean of 70.4 beats per minute. Four of the pulse rates are 83, 75, 91, and 51.

a. Find the missing value.

b. Suppose that you need to create a list of n values that have a specific known mean. Some of the n values can be freely selected. How many of the n values can be freely assigned?

---

**a. The missing value is \_\_\_ beats per minute.**

(Type an integer or a decimal. Do not round.)

**b. Select the correct choice below and fill in the answer box to complete your choice.**

(Type an expression using n as the variable.)

- A. Of the n values, \_\_\_ can be freely selected because the remaining value(s) must be equal to the known mean.

- B. Of the n values, \_\_\_ can be freely selected because the remaining value(s) can be expressed in terms of the mean, median, and midrange of the assigned values.

- C. Of the n values, \_\_\_ can be freely selected because the remaining value(s) can be expressed in terms of the assigned values and the known mean.
