STATISTICS FOR MGT DECISIONS FINAL query Forecasting Simple Linear naive backsliding Applications Interpretation and Use of Computer Output (Results) NAME component A REGRESSION ANALYSIS AND FORECASTING 1) The direction of an international hotel chain is in the process of evaluating the mathematical sites for a spic-and-span unit on a beach re port. As part of the analysis, the steering is kindle in evaluating the family birth between the outmatch of a hotel from the beach and the hotels average occupancy locate for the season. A sample of 14 existing hotels in the area is chosen, and each hotel reports its average occupancy prescribe.The management records the hotels distance (in miles) from the beach. The following set of data is obtained length (miles)0. 10. 10. 20. 30. 40. 40. 50. 60. 7 Occupancy (%)929596908996908385 Continue infinite (miles)0. 70. 80. 80. 90. 9 Occupancy (%)8078767275 Use the computer output to respond to the following questions a) A unsoph isticated elongate arrested development was ran with the occupancy invest as the dependent (ex homeyed) varying and distance from the beach as the breakaway (ex obviousing) inconstant Occpnc=bpic+bpic(Distncy) What is the guessd regression equation?The regression model is Occpnc = bpic + bpic(Distncy) The numberd regression equation is OCCUPNC = 99. 61444 26. 703 DISTNCY b) Interpret the meaning poop the values you get for both coefficients bpic and bpic. bpic=99. 61444, represent the y-intercept as well as the starting figure for the distance coverage. This is the amount of distance in miles that the hotel is from a beach. bpic = 26. 703, represents the percentage of occupancy a hotel has depending on the distance of the hotel from a beach. c) What straighten out of relationship exists between average hotel occupancy footstep and the hotels distance from the beach?Does this relationship make aesthesis to you? why or why not? Both distance and occupancy gift a direct r elationship. This is true because closer the hotel is to the beach, the high the chance that the hotels occupancy leave alone be greater. If a somebody is discharge to stay at a hotel, chances are they are on vacation. stack on vacation love to spend time on a beach for relaxation purposes, so it would only make smell that a hotel that is closer to the beach willing nurse a high(prenominal) occupancy rate. d) Interpret the R-Square value in your computer output R-Squared = 0. 848195 = 84. 8195 ) Predict the expected occupancy rate for a hotel that is (i) one mile from the beach in that area, (ii) one and half miles from the beach. i.

OCCUPNC = 99. 61444 26. 703 (1. 5) = 99. 61444 40. 055 = 59. 559 f) In your mind, what other variables raise positively or negatively to hotel occupancy besides distance from the beach? Other variables that sacrifice positively or negatively to hotel occupancy besides distan ce from the beach hold the distance of restaurants, shopping centers, and airdrome from the hotel.The closer theses variables are to the hotel the chances the occupancy rate will be higher(prenominal). In addition, other variables whitethorn accept what type of amenities that are offered by the hotel, customer service, and rating of the hotel. g) At a level of significance, ? = 0. 01 or 1 percent test the following pair of hypotheses Hpic bpic= 0 Hpic bpic? 0 On the model Occpnc=bpic+bpic(Distncy) What is your induction and why that particular induction? computing machine OUTPUT PART 1 INTERNATIONAL HOTEL REGRESSION affair & ANOVA FOR OCCPNCY OCCPNCY = 99. 61444 26. 703 DISTANCER-Squared = 0. 848195 Adjusted R-Squared = 0. 835545 Standard error of number = 3. 339362 deed of cases used = 14 summary of division p-value Source SS df MS F Value Sig Prob retroversion 747. 68 1 747. 68390 67. 04880 0. 000002 sleep 133. 82 12 11. 15134 Total 881. 50 13 computing device OUTP UT PART 1 INTERNATIONAL HOTEL REGRESSION COEFFICIENTS FOR OCCPNCY bilaterally symmetric p-value changeable Coefficient Std flaw t Value Sig Prob Constant 99. 61444 1. 4107 51. 31933 0. 000000 DISTANCE -26. 70300 3. 26110 -8. 18833 0. 000002 * Standard error of picture = 3. 339362 Durbin-Watson statistic = 1. 324282 quaternary REGRESSION 2) You want to find out factors that explain an individuals weekly nest egg.

This makes sense because if the price is lower, a person will purchase more items. c) What can you say about GOOD Y and GOOD X (a respectable can be an item, a commodity, etc. ).

Suppose the price of glass is $0. 50/lb, the sales of the sweeten versus the same type of edulcorate that is $0. 80/lb would yield more sales because of the price. The price of the glass over directly affects sales in this instance because a person would buy more candy at $0. 0/lb versus $0. 80/lb. 4) REGRESSION ANALYSIS A business person is trying to estimate the relationship between the price of good X and the sales of good Z of certain groups of staples.

SALES (Z) = 1740. 686 + 115. 5882 PRICE(X) b) What sort of relationship exists between SALES OF Z and the PRICE OF X? Does this relationship make sense? Why or why not? There is a direct relationship between gross sales of Y and the Price of X. The higher the price the higher are the sales. This makes sense as it relates to supply and demand. The higher the demand and for the product and unavailability of the product, the price will go up even though sales may he same due to the price increase the sales amount will be higher. c) What can you say about GOOD Z and GOOD X (a good can be an item, a commodity, etc. ). Give an example of good X and good Z that can queer this kind of relationship A prime example that displays this kind of relationship is gas. The price of gas has been exhalation up for sometime now. The demand for it is high, but the supply of is low. Therefore, even though the amount of sales may stay constant, the dollar amount will be higher because the price is higher.
