XYZ hotel uses approximately 200 towels daily. It operates 250 days a year. Assuming, lead time is normally distributed with a mean of 2 days and a standard deviation of 0.5 day. The management desires 90 percent service level. Annual carrying costs is $0.8 per towel, and ordering costs is $20. Given the production rate for the towel = 600 towels per day.

1. Determine the optimal order quantity?
2. Determine Safety Stock?
3. The sales people have recently told the top management that they could expect $200 improvement in profit if the service level were increased to 99%. Is it worthwhile for XYZ hotel to make this change?

6 Food AND Beverage

As you learned in your Reading, procurement or purchasing is the precursor to the rest of the foodservice management system. In this Journal assignment, you will decide both a purchasing method and process based on your understanding of the readings. Read the scenario and address the checklist items in a thorough response. Scenario: You are the new Beverage Manager at a new large hotel that has banquets and has several restaurants. You are tasked with deciding on the purchasing method and process for purchasing all the alcoholic beverages at the hotel. Checklist: Identify and explain the purchasing method will you use and why. Provide the purchasing process will you use and explain why.

The following linear regression model can be used to predict ticket sales at a popular water park (the correlation is significant).

Ticket sales per hour = -631.25 + 11.25(current temperature in °F)

Choose the statement that best reflects the meaning of the slope in this context.

Group of answer choices

The slope is slippery.

The slope tells us that a one degree increase in temperature is associated with an average increase in ticket sales of 11.25 tickets.

The slope tells us that if ticket sales are decreasing there must have been a drop in temperature.

The slope tells us that high temperatures are causing more people to buy tickets to the water park.

At year-end (December 31), Chan Company estimates its bad debts as 0.60% of its annual credit sales of $665,000. Chan records its Bad Debts Expense for that estimate. On the following February 1, Chan decides that the $333 account of P. Park is uncollectible and writes it off as a bad debt. On June 5, Park unexpectedly pays the amount previously written off.
Prepare Chan's journal entries for the transactions.

• Record the estimated bad debts expense.
• Wrote off P. Park's account as uncollectible.
• Reinstated Park's previously written off account.
• Record the cash received on account.

QUESTION TWO
Suppose that the operations manager of a nose mask packaging delivery service is
contemplating the purchase of a new fleet of trucks during this COVID-19 period. When
packages are efficiently stored in the trucks in preparation for delivery, two major constraints
have to be considered. The weight in pounds and volume in cubic feet for each item. Now
suppose that in a sample of 200 packages the average weight is 26.0 pounds with a standard
deviation of 3.9 pounds. In addition suppose that the average volume for each of these
packages is 8.8 cubic feet with standard deviation of 2.2 cubic feet. How can we compare the
variation of the weight and volume?

QUESTION THREE
The marketing director of GH HOTEL was interested in studying the intention of consumers
to visit their facility after the president has fully lifted the restriction on public gathering in
2020 and as a follow- up, whether they in fact actually visited. Suppose that a sample of 1000
household was initially selected and the respondents were asked whether they planned to visit
GH HOTEL. Twelve months later the same respondents were asked whether they actually
visited the hotel. The results are summarized in the table below
Planned to visit
Actual visit
Yes No Total
Yes 200 50 250
No 100 650 750
Total 300 700 1000
i. Draw a tree diagram to represent the information in the table.
ii. Find the probability of selecting a respondent who actually visited GH HOTEL.
Interpret your answer in a simple single sentence.
iii. Find the probability of panned visit or actual visit.
iv. Calculate the probability that a respondent actually visited GH HOTEL given that he
or she planned to visit GH HOTEL

"Vehicles are prohibited on the paths in the park" is used as an example of a law that might require clarification.

Decide whether the law should be interpreted to forbid motorcycles, bicycles, children's pedal cars, and battery-powered remote-control cars. On what grounds are you deciding each of these cases?

Investigation B, The Braun Electroscope

       The Braun electroscope consists of a metal disc at the upper end of a metal rod insulated from the case of the instrument. The rod supports a light metal vane free to rotate about a horizontal axis. When the electroscope is charged the vane swings from its normal vertical position to a near equilibrium position. The angle it makes with the vertical is proportional to the charge of the electroscope.

1            A. Ground the electroscope by touching the disc.

B. Bring a negatively charged rod near the disc of the electroscope.

C. Remove the rod.

2            A. Ground the electroscope.

B. Bring a negatively charged rod near the disc of the electroscope.

C. Touch the rod to the disc. This is charging by contact.

D. Remove the rod.

3   A. Charge the electroscope as in 7, by contact.

B. Bring the negatively charged rod to within 5 cm. of the disc of the electroscope.

C. Bring the negatively charged rod as close to the disc as possible without a spark jumping from the rod to the disc.

D. Remove the rod.

4   A. Charge the electroscope as in 7, by contact.

B. Bring a positively charged rod to within about 5cm. of the disc of the electroscope.

C. Bring a positively charged rod as close to the disc of the electroscope as possible without a spark jumping from the rod

D. Remove the rod.

5     A. Ground the electroscope.

      B. Bring a negatively charged rod near the disc of the electroscope.

      C. keeping the rod near the disc, ground the telescope.

      D. Keeping the rod near the disc, removes the grounding connection.

      E. Remove the rod. The electroscope has been charged by induction.

6     A. Charge the electroscope by induction as 10 observing carefully the charging distance between rod and disc when the electroscope is grounded.

B. Bring a negatively charged rod near the disc. Draw diagrams for the following cases:

1) Rod beyond the charging distance.

2) Rod at charging distance.

3) Rod inside the charging distance.

C. Remove the rod.

7      A. Charge the electroscope by induction as in 10.

       B. Bring a positively charged rod near the electroscope.

       C. Remove the rod.

Note: the experiments above might be repeated, replacing a positive with a negative rod and a negative with a positive rod. In all cases the charge distribution would be opposite to that for the above experiments.

8. Charge the electroscope positively by induction. Record the electroscope positively by induction. Record the effect of bringing the hand near the knob of the electroscope.

Charge the electroscope negatively by induction. Record the effect of bringing the hand near the electroscope. Diagrams need not be drawn for this part.

The prof reuqire us to explain which situation !~~ Please help

Markets generally lead to efficient use and allocation of resources, but sometimes at the cost of equity. Many have observed a trade-off between efficiency and equity, or growth in income and wealth inequality as the economy becomes more efficient.

Bill Gates made the following statement: "Yes, some level of inequality is built into capitalism.... It is inherent to the system. The question is, what level of inequality is acceptable? And when does inequality start doing more harm than good?"
