The goal is to estimate the average length of the N strings in the bag the instructor is holdling. The sampling will be done by two different methods, both involving randomization.
1. Selection by touch
a. Without looking into the bag reach into it and select a string. Record its length (to the nearest inch) and return the string to the bag. Repeat this process until 10 strings have been sampled.
b. Calculate the average of your sampled string lengths.
c. Report your average to the instructor, who will provide you with all the aver, ages recorded in the class.
