Ten values have a mean of $75.0 .$ Nine of the values are 62,78 $90,87,56,92,70,70,$ and 93 a. Find the 10 th 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 $n$ values can be freely assigned before the remaining values are determined? (The result is often referred to as the number of degrees of freedom.)
