1. Unable to find a random number of tables, a desperate AP Statistics student decided to make a random list by guessing numbers. The results are below, showing the number of times each integer occurred in a sample size n = 50. If the collection of last digits is random, then we would expect each integer to occur, on average, equally often.

Integer 0 1 2 3 4 5 6 7 8 9

Frequency 0 3 6 5 5 5 0 10 8 8

Do the observed frequencies meet this expectation? Perform the appropriate test and report your findings. Be sure to include all the necessary steps. (10 points)
