Scatter Plot **Problem 10:** In a study of check scanning systems, samples of purchases were used to compare the scanned prices vs. posted and advertised prices. The table below summarizes results for a sample of 819 items scanned. Based on the data presented, what is the probability that a regular-priced item had a scanning error? What is the probability that an advertised-special item had a scanning error? Any additional comments on customer impact from your review of the data?--- This exercise set aims to help students apply concepts of probability, normal distribution, and data visualization in practical scenarios.
