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…

The operations manager of a company that manufactures tires wants to determine whether there are any differences in the quality of workmanship among the three daily shifts. She randomly selects 499 tires and carefully inspects them. Each tire is either classified as perfect, satisfactory, or defective, and the shift that produced it is also recorded. The two categorical variables of interest are: shift and condition of the tire produced. The data can be summarized by the accompanying two-way table. Perfect Satisfactory Defective Total Shift 1 106 124 2 232 Shift 2 66 85 3 154 Shift 3 36 74 3 113 Total 208 283 8 499 A) This sample has degree of freedom:��= If shift and quality are independent, thenB) With any expected count accurate to 2 decimal places, the expected count in row 1 column 1 is�1,1= C) With any component accurate to 2 decimal places, the component value in row 1 column 1 of the table iscomponent1,1= D) �2 value of this sample is�2= .

A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.
