Speedy Swift is a package delivery service that serves the greater Atlanta, Georgia, metropolitan area. To maintain customer loyalty,
one of Speedy Swift's performance objectives is on-time delivery. To monitor its performance, each delivery is measured on the
following scale: early (package delivered before the promised time), on-time (package delivered within 15 minutes of the promised
time), late (package delivered more than 15 minutes past the promised time), or lost (package never delivered). Speedy Swift's
objective is to deliver 99% of all packages either early or on-time. Another objective is to never lose a package.
Speedy collected the following data for last month's performance:

Faschip, Ltd., is a new African manufacturer of notebook computers. Their quality target is that 99.999% of the computers they produce will perform exactly as promised in the descriptive literature. In order to monitor their quality performance they include with each computer a large piece of paper that includes a direct—toll-free—phone number to the Senior Vice President of Manufacturing that can be used if the computer does not perform as promised. In the first year Faschip sells 1,000,000 computers.a. If they are achieving their quality target, what is the probability that they will receive fewer than 5 calls? If this occurs what would be a reasonable conclusion about their quality program? b. If they are achieving their quality target, what is the probability that they will receive more than 15 calls? If this occurs, what would be a reasonable conclusion about their quality program?
Patrick is a human resources director. His firm has recently started offering a retirement plan, and he has
asked shift supervisors to meet with employees to encourage them to sign up. Every week, shift
supervisors report the number of employees with whom they have talked. He has a spreadsheet of
employees signing up for the retirement plan compared to the number of employees that have been
contacted. Below is the scatterplot of each shift's sign-up percentage during the last several months.
Using the information provided, what would be a good course of action for Patrick to take?

- The Lawson Fabric Mill Produces five different fabrics. Each fabric can be woven on one or more of the mill’s 36 looms. The sales department’s forecast of demand for the next month is shown in below Table 1, along with data on the selling price per yard, variable cost per yard, and purchase price per yard. The mill operates 24 hours a day and is scheduled for 30 days during the coming month. The mill has two types of looms: draw and regular. The draw looms are more versatile and can be used for all five fabrics. The regular looms can produce only three of the fabrics. The mill has a total of 36 looms: 8 are draw and 28 are regular. The rate of production for each fabric on each type of loom is given in below Table 2. The time required to change over from producing one fabric to another is negligible and does not have to be considered. The Lawson Fabric Mill satisfies all demand with either its own fabric or fabric purchased from another mill. Fabrics that cannot be woven at the…arrow_forwardSleep Late, a large hotel chain, has been using activity-based costing to determine the cost of a night’s stay at their hotels. One of the activities, “Inspection,” occurs after a customer has checked out of a hotel room. Sleep Late inspects every 10th room and has been using “number of rooms inspected” as the cost driver for inspection costs. A significant component of inspection costs is the cost of the supplies used in each inspection Mary Adams, the chief inspector, is wondering whether inspection labor-hours might be a better cost driver for inspection costs. Mary gathers information for weekly inspection costs, rooms inspected, and inspection labor-hours as follows: Q.Plot the data and regression line for rooms inspected and inspection costs. Plot the data and regression line for inspection labor-hours and inspection costs. Which cost driver of inspection costs would you choose?

During the day, the demand for nurses varies. Maureen has broken the day into twelve 2hour periods. The slowest time of the day encompasses the three periods from 12:00 A.M. to 6:00 A.M., which, beginning at midnight, require a minimum of 30, 20, and 40 nurses, respectively. The demand for nurses steadily increases during the next four daytime periods. Beginning with the 6:00 A.M.–8:00 A.M. period, a minimum of 50, 60, 80, and 80 nurses are required for these four periods, respectively. After 2:00 P.M. the demand for nurses decreases during the afternoon and evening hours. For the five 2-hour periods beginning at 2:00 P.M. and ending at midnight, 70, 70, 60, 50, and 50 nurses are required, respectively.

- Arianna Estefan manages Salmon Falls Park, which has two flagship roller coasters, the Flyer and the Destroyer. When Arianna walks around the park during hours of operation, she notices that there are fewer people waiting in line for the Flyer than for the Destroyer. Since both roller coasters have similar capacities and similar run times, both roller coasters should have about the same number of riders. Based on the anecdotal evidence, Arianna claims that the population mean number of riders per hour on the Flyer is less than the population mean number of riders per hour on the Destroyer. Arianna reviews data collected in the past and assumes that the population standard deviation is 48.29 for the Flyer and 51.86 for the Destroyer. Arianna randomly selects hours during which the attendant of each ride counts the number of riders. The sampling occurs over the course of several weeks. The results are provided in the table shown below.

He is also a basketball fan. One day her gym teacher assigned her to report the average points earned by women's basketball players in each game in the form of a written report. Then Sergei took 10 player names and their points in one game. He took data from the WNBA AIl-Times Leaders website, based on this data in this regular season Nykesha Sales got 14.2 points per game, Sophia Young-malcolm got 14.3; Kayla McBride got 14.5; DeWanna Bonner got 14.8; Napheesa Collier got 14.9; Sheryl Swoopes got 15.0; Tina Thompson gets 15.1; Jewell Loyd gets 15.2 points; Kelsey Mitchell gets 15.2 points; and Seimone Augustus got 15.4 points. If it is claimed that the population mean is 14 points in each game, the alternative is greater than the null hypothesis. Perform a unidirectional test of the results of the sample taken by Sergei lvanovich with a significance level of 0.01.arrow_forward

- Charity Navigator is America's leading independent charity evaluator. The following data show the total expenses (), the percentage of the total budget spent on administrative expenses, the percentage spent on fundraising expenses, and the percentage spent on program expenses for supersized charities. Administrative expenses include overhead, administrative staff and associated costs, and organizational meetings. Fundraising expenses are what a charity spends to raise money, and program expenses are what the charity spends on the programs and services it exists to deliver. The sum of the three percentages does not add to because of rounding. # Charity Total Expenses($) AdministrativeExpenses(%) FundraisingExpenses(%) ProgramExpenses(%) 1 American Red Cross 3,354,177,445 3.9 3.8 92.1 2 World Vision 1,205,887,020 4.0 7.5 88.3 3 Smithsonian Institution 1,080,995,083 23.5 2.6 73.7 4 Food For The Poor 1,050,829,851 0.7 2.4 96.8 5 American…arrow_forwardThe Conch Café, located in Gulf Shores, Alabama, features casual lunches with a great view of the Gulf of Mexico.
