2. Baldur is a big fan of salaries. He collects data on wages and the length of schooling the people had from 100 employees in a large company with the aim of creating a model that can predict wages by level of education (measured in the number of years in school after primary school). The employees with the lowest level of education in Baldur's data immediately entered the labor market after compulsory school leaving, while those with the highest level of education have completed 9 years of schooling after leaving compulsory school leaving. Baldur started by drawing the data and saw that the relationship is linear. He also calculated some fish sizes that can be seen below: standard Change average deviation salary 660020 150100 Education (year from primary school diploma) 5.5 2.2 He also calculated the correlation coefficient between salary and level of education (measured in the number of years in school from primary school exam) and obtained r = 0.55. a.) Find the equation regression…
3. Research Problem Job satisfaction as a function of work schedule waS investigated in two different factories. In the first factory the employees are on a fixed shift system while in the second factory the workers have a rotating shift system. Under the fixed shift system, a worker ahways works the same shift, while under the rotating shift system, 8 worker rotates through the three shifts. Using the scores below determine if there is a significant difference in job satisfaction between the two groups of workers.

Case. 15.1. Ski Jacket Production. Egress, Inc., is a small company that designs, produces, and sells ski jackets and other coats. The creative design team has labored for weeks over its new design for the coming winter season. It is now time to decide how many ski jackets to produce in this production run. Because of the lead times involved, no other production runs will be possible during the season. Predicting ski jacket sales months in advance of the selling season can be quite tricky. Egress has been in operation for only three years, and its ski jacket designs were quite successful in two of those years. Based on realized sales from the last three years, current economic conditions, and professional judgment, 12 Egress employees have independently estimated demand for their new design for the upcoming season. Their estimates are listed in Table 15.2 To assist in the decision on the number of units for the production run, management has gathered the data in Table 15.3. Note that S…

Match the description on the right with the correct term on the left regarding types of forecasting methods. 1. Econometric, input-output, and simulation are techniques used with this type of forecasting method, which assumes that the variable to be forecasted is related to one or more intrinsic variables. Causal Methods 2. The Delphi technique, market surveys, and life-cycles analogy are techniques used with this type of forecasting method, which relies on the judgment of individuals or Qualitative Methods Time-Series Methods groups. 3. Moving averages and exponential smoothing are techniques used with this type of forecasting method, which assumes that time is the only important variable.

1. Here is data testing dosage amounts for a new drug used to treat pain. Due to its recent development, researchers want to know what is the appropriate dosage to treat chronic pain in arthritis patients. Each participant was given either a sugar pill, 50 mg, or 100 mg of the new medication. It is predicted that the 50 mg will be more effective than the placebo, and the 100 mg will be more effective than both the placebo and 50 mg. After a month, each participant rated their pain level. The higher the value, the more pain they felt. Use alpha = .05 Placebo/Sugar Pill 50 mg 100 mg X1 = 14 SS, = 932 X2 = 12 X3 = 7 SS2 = 654 SS3 = 620 ni = 40 n2 = 40 n3 = 40 SS Total 3106 A. State the hypotheses. B. Make a decision about the null. C. State your conclusion. D. Relate your conclusion to the research. E. If allowed, conduct analytical comparisons. a. State the hypotheses. b. Make a decision about the null. c. State your conclusion. d. Relate your conclusion to the research.
