Please dont write on a piece of paper and take a screen shot of it. Round to 3 decimal places. This includes in the middle of calculations and your final results.

1) The scores on an ethics exam are approximately normally distributed. Fred's score was one standard deviation below the mean. What percent of test takers scored below Fred's score?

9) You need to implement an automated customer service phone system. You are considering two options. You pilot System A with 30 randomly selected customer service representatives and System B with a separate set of 30 randomly selected representatives. After each call, customers are asked to rate their satisfaction on a scale of 1 (low) to 10 (high) and you calculate the average satisfaction score for each representative after 2 weeks. Use the "customer satisfaction" DATA BELOW to conduct a hypothesis test to see if the average satisfaction score is different between the two systems. Use a 95% confidence level, state your hypotheses, and document the important pieces of the R Studio output (do not just include a screenshot).
