Question

Looking for instructions

The wedding date for a couple is quickly approaching, and the wedding planner must provide the caterer an estimate of how many people will attend the reception so that the appropriate quantity of food is prepared for the buffet. The following table contains information on the number of RSVP guests for the 140 invitations. Unfortunately, the number of guests does not always correspond to the number of RSVPed guests. Based on her experience, the wedding planner knows it is extremely rare for guests to attend a wedding if they notified that they will not be attending. Therefore, the wedding planner will assume that no one from these 40 invitations will attend. The wedding planner estimates that the each of the 30 guests planning to come solo has a 75% chance of attending alone, a 15% chance of not attending, and a 10% chance of bringing a companion. For each of the 60 RSVPs who plan to bring a companion, there is a 85% chance that she or he will attend with a companion, a 10% chance of attending solo, and a 5% chance of not attending at all. For the 10 people who have not responded, the wedding planner assumes that there is an 75% chance that each will not attend, a 15% chance each will attend alone, and a 10% chance each will attend with a companion.

Assist the wedding planner by constructing a spreadsheet simulation model to determine the expected number of guests who will attend the reception. Round your answer to 2 decimal places. ___________ guests

To be accommodating hosts, the couple has instructed the wedding planner to use the Monte Carlo simulation model to determine X, the minimum number of guests for which the caterer should prepare the meal, so that there is at least a 90% chance that the actual attendance is less than or equal to X. What is the best estimate for the value of X? Round your answer to the nearest whole number. ____________guests

Answer 1

The guests are approximately 140 invi Based on her experience , she thought all are attend ..4500 chance of attending alone. 150 chance of not attending. 10.1 chance of bringing a Companion.
