Suppose that the number of customers who enter a supermarket each hour is normally distributed with a mean of 640 and a standard deviation of 240. The supermarket is open 17 hours per day. What is the probability that the total number of customers who enter the supermarket in one day is greater than 10200? (Hint: Calculate the average hourly number of customers necessary to exceed 10200 in one 17-hour day.) Probability = ?? ______

1. A gas station opens at a time which is Normally distributed with the mean of 8:45 am and standard deviation of 10 minutes; similarly, its closing time is Normally distributed with the mean value at 5:12 pm and standard deviation of 15 minutes. If customers arrive as a Poisson Process with an average rate of 11.3 per hour, find the mean number of customers to be served in one such day, and the corresponding standard deviation. What is the...
The number of beverage cans produced each hour from a vending machine is normally distributed with...
The number of beverage cans produced each hour from a vending machine is normally distributed with a standard deviation of 8.6. For a random sample of 12 hours, the average number of beverage cans produced was 326.0. Construct a 99% confidence interval for the population mean number of beverage cans produced per hour.
The demand for a particular type of yogurt in a supermarket is normally distributed with a...
The demand for a particular type of yogurt in a supermarket is normally distributed with a mean of 80 units per day and a standard deviation of 4 units per day. Lead time for delivery of the yogurt is 4 days. The supermarket uses a fixed order size of 92 units for yogurt orders. The ordering cost is $30 per order and the annual cost of holding inventory is $1/unit. Assume 300 days per year. if the manager wants a...

1. The number of hours spent sleeping each day by teens is normally distributed with a mean of 9 hours and a standard deviation of 1.8 hours a) Find the probability one teen will sleep over 10 hours in day? b) If I take a sample of 100 teens, how many of those 100 teens on average will sleep over 10 hours in day?
Suppose the amount of time a doctor spends with their patients is normally distributed with a...
Suppose the amount of time a doctor spends with their patients is normally distributed with a mean of 17.4 minutes and with standard deviation of 3.8 minutes. Suppose 26 patients have scheduled appointments on one day. What is the probability that the mean amount of time for those 26 patients is less than 18.5 minutes, which would be equivalent to the doctor seeing patients for 8 hours and 1 minute that day.
Customers enter a store according to a Poisson process of rate λ = 5 per hour....
Customers enter a store according to a Poisson process of rate λ = 5 per hour. Independently, each customer buys something with probability p = 0.8 and leaves without making a purchase with probability q = 1 − p = 0.2. Each customer buying something will spend an amount of money uniformly distributed between $1 and $101 (independently of the purchases of the other customers). What are the mean and the standard deviation of the total amount of money spent...
