Suppose that for a given city, a grocery store has a 30% chance of having toilet paper in stock. Let X represent the number of grocery stores we must visit until we find the first one that has toilet paper in stock. a) What is the probability distribution of X? b) what is the probability that we must search 2 grocery stores until we find the first one that has toilet paper? c) what is the probability that we must...
A local store sells toilet paper to people in the surrounding communities. The demand for the toilet paper has been increasing and management needs to ensure that enough rolls are available to meet the increasing demand. The daily demand for the toilet paper is 400 rolls. The store operates 250 days per year. The following information is also available about the product. The cost of each roll……………………….…..$2. Ordering costs………………………………..……$100 per order Annual holding costs per unit…………… 10% of the costs...
A grocery store is trying to predict how many packages of toilet paper rolls will be purchased over the next week. They know from their records that each customer has a 60% chance of buying 0 packages, a 30% chance of buying 1 package, an 8% chance of buying 2, and a 2% chance of buying 25. They expect about 150 customers per day. a.) What is the expected number of packages sold in one day? b.) What is the...

The number of visits to a website follows a poisson distribution with an average of 90 per hour. What is the probability that there will be at least 2 visits in one minute? What is the probability that the time between successive visits will be less than 0.5 minutes?
Let x represent the number of times a customer visits a grocery store in a one week period. Assume this is the probability distribution of x: x 0 1 2 3 p(X) 0.1 0.4 0.4 0.1 Find the expected value of x, the average number of times a customer visits the store. 1. 2 2. 0.1 3. 1.5 4. 0.4
Suppose that you have an online blog, and you have observed that the number of visits to your blog follows a Poisson distribution at a rate of 10 visits per day. (a) What is the probability that there will be no hits in the next 6 hours? (b) Suppose that there is no visit in the past 6 hours. What is the probability that you will have to wait for at least 3 more hours till the next visit? (c)...
Jennifer walks behind Sloan's desk and notices that she is looking at the progress notes on a patient who was recently arrested and indicted for child abuse. The case has been in the newspaper and on television consistently for several weeks. Jennifer asks Sloan why she has accessed that record. Sloan hesitates and then says she must have entered the wrong patient ID number. ▪Does Sloan's explanation sound convincing? ▪Why is Jennifer concerned about Sloan looking at the patient's record?...
(a) Visits to a webpage occur on average 4 times in a 2-hour period. What is the probability that a given 30-minute period has no visits? (b) Visits to a webpage occur such that there is a 90% chance that a given hour has at least one visit. What is the probability that a given hour has exactly one visit? (C) What key assumption are you making about the processes in (a) and (b), and why might it be reasonable?
Sam's club sampled 225 customers this week to find out how many packages of toilet paper they purchased. On average, they were purchasing 5 packages, with a standard deviation of 1 package. What is the margin of error of the mean estimate of 5 packages that captures 95% of all values? this is for college stats, thanks
