A. p, the average number of items that had the wrong price scanned at California stores O B. p. the proportion of items in the sample that had the wrong price scanned at California stores O C. z, the test statistic O D. Po, the hypothesized proportion of items that had the wrong price scanned at California stores O E. p. the proportion of items that had the wrong price scanned at California stores b. Set up Ho and H, for a test to determine if the true proportion of items scanned incorrectly at California stores exceeds the 2% NIST standard. What are the hypotheses for this test?
