The operations and management systems in hotels contain the action, strategies and tactics to create a world class customer service experience that is needed for the productivity and development of your hotel. Cutting costs avoid high employee retention and increase reservations and customer stays. The critical factors are quality management, hotel occupancy rates, facilities planning, production planning, and inventory control. The most critical time of the role of operations is the night audit.Please write a 1 page essay explaining operations and management in the hotel industry.

suppose that the hotel acts as a monopolist whose manager chooses what quantity q of rooms to offer for rent. We want to determine the hotel’s optimal choice of quantity on game days.

Consider a hotel which can supply an unlimited number of hotel rooms at the constant marginal cost c = 20 per room per night, so that the hotel’s total cost function is given by C(q) = 20q.1 Assume that demand for hotel rooms in Tallahassee takes two possible values: on game days, demand is described by the demand curve q = 100 − p, while on non-game-days demand is described by the demand curve q = 60 − 2p.

Find the hotel’s total revenue on game days as a function of its quantity choice q. (Recall that total revenue equals price times quantity, where in this case price is described by the inverse demand curve.)

(e) Assuming the hotel maximizes profit, show that it will supply quantity q = 40 on game days.

(f) What will be the hotel price on game days? And what will be the hotel’s game-day profits?

(g) Still focusing on game days, graphically illustrate the demand curve, the hotel’s marginal revenue curve, and the hotel’s marginal cost curve. Indicate the hotel’s optimal quantity and price choices on the graph.

Lilly collects data on a sample of 40 high school students to evaluate whether the proportion of female high school students who take advanced math courses in high school varies depending upon whether they have been raised primarily by their father or by both their mother and their father. Two variables are found below in the data file: math (0 = no advanced math and 1 = some advanced math) and Parent (1= primarily father and 2 = father and mother).

Scenario Suppose that a movie theater faces a downward sloping demand curve for popcorn and it increases the price of a container of popcorn from $4.00 to $4.80, which causes the count of containers sold to fall from 100 to 90.

Questions 1. What is the elasticity coefficient?

2. Is the demand relatively elastic or relatively inelastic?

3. Should the theater consider raising the price of popcorn further?

4. When a firm faces a downward sloping demand curve, should it ever price its product in the inelastic range of the demand curve (if it has such a range)? Explain why or why not.

5. When a firm is a monopolist (or the only seller of a product), should it price its product in the elastic or inelastic range of its demand curve? Explain.

1. Test the claim that the proportion of people who own cats is significantly different than 30% at the 0.2 significance level.
The null and alternative hypothesis would be:

a) H0:μ≤0.3
Ha:μ>0.3

b) H0:p≥0.3
Ha:p<0.3

c) H0:μ≥0.3
Ha:μ<0.3

d) H0:p≤0.3
Ha:p>0.3

e) H0:μ=0.3
Ha:μ≠0.3

f) H0:p=0.3
Ha:p≠0.3


The test is:

-left-tailed

-two-tailed

-right-tailed


Based on a sample of 400 people, 31% owned cats
The p-value is: ____? (to 2 decimals)


Based on this we:

  • Reject the null hypothesis
  • Fail to reject the null hypothesis

2. You wish to test the following claim (HaHa) at a significance level of α=0.01α=0.01.
      Ho:μ=89.7
      Ha:μ≠89.7
You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size n=12 with mean M=93.7 and a standard deviation of SD=8.6

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value = ______?
The p-value is...

  • less than (or equal to) αα
  • greater than αα

This p-value leads to a decision to...

  • reject the null
  • accept the null
  • fail to reject the null

As such, the final conclusion is that...

  • There is sufficient evidence to warrant rejection of the claim that the population mean is not equal to 89.7.
  • There is not sufficient evidence to warrant rejection of the claim that the population mean is not equal to 89.7.
  • The sample data support the claim that the population mean is not equal to 89.7.
  • There is not sufficient sample evidence to support the claim that the population mean is not equal to 89.7.
