He thinks that. on average. 60% ofthe daily customers come between 6:00pm and 8:59pm {equally distributed in that time) and the remaining 40% of customers come at other times during the operating hours (again equally distributed). He wants to verify if that is true or not. so he asked his staff to write down during one week the number of customers that come into the restaurant at a given hour each day. His staff gave him the following data: Time Day 1 Day 2 Day a Day 4 Day 5 Day a Day 7 5:00pm-5:59pm 1s 19 21 211 12 15 1s 6:00pm-S:59pm so 23 24 25 23 29 25 7:00pm-7:59pm 36 29 39 35 39 30 32 23 29 24 32 27 a:00pm-B:59pm 29 9:00pm-9:59pm 21 20 12 19 1a 14 20 10:00pm-10:59pm 12 12 15 12 1D 15 14 11 :00pm-1'l :59prn a 7 9 1o 12 12 e a Help the manager figure out if his instincts are correct or not.

The restaurant is famous for its Lobo lobster roll. You were given some information based on which you deduced that the demand for the lobster roll was normally distributed with a mean of 220 and standard deviation of 50. You also know that the lobster supplier can provide lobster at a rate that mimics a uniform distribution between 170 and 300. One Lobster is used per roll and the lobsters need to be fresh (Le. the restaurant can only use the lobsters that are delivered that day]. You decide to run 200 simulations of 1000 days each. Calculate the expected sales of Lobster roll per clay based on your simulation results. Enter your answer rounded to the nearest whole number. For example. if your answer is 12.3456, you should enter 12 in the box below. 202 V 202 Use the expected sales from each ofyour 200 simulations to create a condence interval for the average expected sales. What is the 95% confidence interval, L (Your confidence interval is mean +17 L}, for this estimate? Enteryour answer rounded to two decimal places. For example, ifyour answer is 123455, you should enter 12.35 in the box below. I: Enregistrer
