A small, independent amusement park collects data on the number of cars with out-of-state license plates. The sample size is fixed at n=100 each day. Data from the previous 10 days indicate the following number of out-of-state license plates: Day 1 2 3 4 5 6 7 8 9 10 Out-of-state Plates 6 4 5 7 8 3 4 15 3 11 (a) Calculate the overall proportion of "tourists" (cars with out-of-state plates) and the standard deviation of proportions. (b) Using +36 limits, calculate the LCL and UCL for these data. (c) Is the process under control? Explain.
