Question 2

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=25 each day.Data from the previous 10 days indicate the following number of out-of-state license plates:
   (a)Calculate the overall proportion of "tourists" (cars with out-of-state plates)and the standard deviation of proportions.
(b)Using ±3σ limits,calculate the LCL and UCL for these data.
(c)Is the process under control? Explain.

Accepted Answer

(a)p-bar is 56/250 = 0.224;the standard
