Degrees of Freedom Five pulse rates randomly selected from Data Set 1 “Body Data” in Appendix B have a mean of 78.0 beats per minute. Four of the pulse rates are 82, 78, 56, and 84.a. Find the missing value.b. We need to create a list of n values that have a specific known mean. We are free to select any values we desire for some of the n values. How many of the values can be freely assigned before the remaining values are determined? (The result is referred to as the number of degrees of freedom.)
