Question Pete's Market is a small local grocery store with only one checkout counter. Assume that shoppers arrive at the checkout lane according to a Poisson probability distribution, with an arrival rate of 13 customers per hour. The checkout service times follow an exponential probability distribution, with a service rate of 20 customers per hour. The manager’s service goal is to limit the waiting time prior to beginning the checkout process to no more than five minutes. Also the manager of Pete's Market wants to consider one of the following alternatives for improving service. Calculate the value of Wq for each alternative. Hire a second person to bag the groceries while the cash register operator is entering the cost data and collecting money from the customer. With this improved single-server operation, the service rate could be increased to 29 customers per hour. Round your answer to three decimal places. Do not round intermediate calculations.Wq = fill in the blank 1 minutes

QUESTION 37 37. There are three problems: parts 37 to 38, parts 39 to 47, and parts 48 to 51. Read each part of each problem carefully and answer exactly what is asked. For each of the following, there are five (5) possible responses labeled "a" through "e." For each item, mark the letter of your choice which best answers that item. The problems begin with part 37 below. A firm is comparing two designs for a new product, designated "Design 1" and "Design 2." Data concerning the design for disassembly for both designs are provided in the tables below. Design1: Component Resale Revenue per Unit Recycling Revenue per Unit Processing Cost per Unit Disposal Cost per Unit A $5.60 $8.90 $3.50 $2.85 B $2.56 $3.67 $3.25 $2.00 C $1.34 $4.32 $0.69 $3.34 Design 2: Component Resale Revenue per Unit Recycling Revenue per Unit Processing Cost per Unit Disposal Cost per Unit A $4.76 $5.68 $6.00 $2.13 B $3.21 $5.28 $2.42 $3.59 C $5.31 $6.98 $2.47 $4.90 Which design appears to be the best environmental design based on its revenue retrieval? a. Design 1. b. Design 2. c. Either one. d. Neither one. e. Indeterminate. QUESTION 38 For the design selected in part 37, what is the dollar value of the revenue retrieval per unit? a. $8.76 b. $9.71 c. $26.39 d. $31.22 e. $10.76 39. Monthly income in thousands of dollars ($K) at the Acme Law Firm for the six-month period from October (the start of their fiscal year) to March is listed in the table below. month income, $K Oct 69.3 Nov 68.5 Dec 69.6 Jan 71.7 Feb 72.4 Mar 74.8 Using the data in the table, what is the naïve forecast of monthly income for April? (In units of $K, round to two [2] decimal places.) a. $74.80K b. $72.93K c. $73.55K d. $75.11K e. $70.28K

The worldwide market share for the Chrome web browser was 56.43% in a recent month. Suppose that you decide to select a sample of 100 students at your university and you find that 60 use the Chrome web browser. a. Use the five-step p-value approach to determine whether there is evidence that the market share for the Chrome web browser at your university is greater than the worldwide market share of 56.43%. (Use the 0.05 level of significance.) b. Suppose that the sample size is n = 600, and you find that 60% of the sample of students at your university (360 out of 600) use the Chrome web browser. Use the five-step p-value approach to try to determine whether there is evidence that the market share for the Chrome web browser at your university is greater than the worldwide market share of 56.43%. (Use the 0.05 level of significance.) c. Discuss the effect that sample size has on hypothesis testing. d. What do you think are your chances of rejecting any null hypothesis concerning a population proportion if a sample size of n = 20 is used?

Find the magnitude of the resultant force and the angle it makes with the positive x-axis. (Let a = 26 lb and b = 12 lb. Round your answers to one decimal place.)

Harley-Davidson is known for its strong brand name and loyal following and yet by 1980 Harley was on the verge of bankruptcy. Why was Harley in deep trouble even with such a strong brand name? a) Harley-Davidson cannot compete in foreign markets b) Competitors beat Harley on reliability and cost c) All of the above d) Harley-Davidson bikes are technologically inferior COURSE: STRATEGIC BUSINESS DECISIONS

Suppose that a wind is blowing in the direction S45°E at a speed of 30 km/h. A pilot is steering a plane in the direction N60°E at an airspeed (speed in still air) of 200 km/h. The true course, or track, of the plane is the direction of the resultant of the velocity vectors of the plane and the wind. The ground speed of the plane is the magnitude of the resultant. Find the true course and the ground speed of the plane. (Round your answers to one decimal place.)
