A performance evaluation for new sales representatives at Office Automation Incorporated involves several ratings done on a scale of 1 to 10, with 10 the highest rating. The activities rated include new contacts, successful contacts, total contacts, dollar volume of sales, and reports. Then an overall rating is determined by using a weighted average. The weights are 3 for new contacts, 1 for successful contacts, 4 for total contacts, 3 for dollar value of sales, and 5 for reports. What would the overall rating be for a sales representative with ratings of S for new contacts, 7 for successful contacts, 6 for total contacts, 2 for dollar volume of sales, and 4 for report:?

Students at a major university in Southern California are complaining about a serious housing crunch. Many of the university's students, they complain, have to commute too far to school because there is not enough housing near campus. The university officials' response is to perform a study. The study, reported in the school newspaper, contains the following histogram summarizing the commute distances for a sample of 100 students at the university: Frequency 30- 27 25- 24 19 20+ 15- 14 11 10- 5 5- 4 12 16 20 24 Commute distance (in miles) Based on this histogr draw the ogive (the cumulative frequency polygon) for the data in the study.

Analyze Valley Hospital's admissions time variance Valley Hospital began using standards to evaluate its Admissions Department. The standard was broken into two types of admissions as follows: The unscheduled admission took longer because name, address, and insurance information needed to be determined and verified at the time of admission. Information was collected on scheduled admissions prior to admitting the patient, thus requiring less time in admissions. The Admissions Department employs two full-time people for 40 hours per week at $15 per hour. For the most recent week, the department handled 66 unscheduled and 120 scheduled admissions. a. How much was actually spent on labor for the week? $b. What are the standard hours for the actual volume of work for the week? (Round to the nearest whole hour.) hours c. Compute the direct labor time variance, and report how well the department performed for the week. In your computation, round the standard direct labor rate to the nearest…
Attractiveness of body types has been a large discussion relating to effects on youth and culture. Unhealthy levels of BMI are often associated with beauty. A researcher decided to study how young heterosexual adults body type preferences related to BMI. Participants were asked to use a computer program to design their desired partner. The program then calculated the BMI of the designed partners. The table summarizes the results based on a SRS of 35 men and 48 women. BMI designed by men n=35 x-bar=18.850 stdev=1.750 SE Mean 0.277 BMI designed by women n=48 x-bar=25.860 stdev=4.215 SE Mean 0.625 Use this information to conduct a test to decide if male and/or female body type preferences are associated with healthy BMI measurements. You should have two complete tests here. You may assume the populations are normally distributed.

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).
