Claire works at Red Robin every weekend serving about 30 tables. It is estimated that the average tip amount she gets per table follows a normal distribution with an average of S8.25 and a standard deviation of $1.50 a) b) c) Draw a normal curve that describes her tip amount on average. What is the probability that the average tip amount is between $ 5.25 and $11.25? On average, how much does she make per table during her best 10% of weekends? What is the probability that she cams a total of $250 for 30 tables? [ Hint multiply the mean and standard deviation by 30 and then find the z-score]?
