**Performance Review Guidelines for University Supervisors**Most organizations use some form of year-end performance review for their employees. Human Resources (HR) at a university's Health Science Center provides guidelines for supervisors rating their subordinates. For example, raters are advised to examine their ratings for a tendency to be either too lenient or too harsh. According to HR:"If you have this tendency, consider using a normal distribution—10% of employees (rated) exemplary, 20% distinguished, 40% competent, 20% marginal, and 10% unacceptable."Suppose you are rating an employee's performance on a scale of 1 (lowest) to 100 (highest). Also, assume the ratings follow a normal distribution with a mean of 46 and a standard deviation of 13. Complete parts a and b.Click the icon to view the standard normal distribution table.**Questions:**a. What is the lowest rating you should give to an "exemplary" employee if you follow the university's HR guidelines?*(Round to three decimal places as needed.)*[ ] b. What is the lowest rating you should give to a "competent" employee if you follow the university's guidelines?*(Round to three decimal places as needed.)*[ ] This exercise involves understanding normal distribution and applying statistical principles to determine appropriate performance ratings. Using the provided mean and standard deviation, along with the mentioned percentiles (e.g., top 10% for exemplary), you can derive the specific ratings that correspond to these performance categories.

You want to compare males and females in their use of coping strategies when engaged in conflict in relationships. You send surveys to couples obtained from marriage license application at the county clerk's office. You identify several distinct coping strategies on the survey and have the respondents rate their use of each strategy on a 7-point scale. You then compare scores that come from the two members of each relationship. If testing hypotheses about the effects of gender on use of coping strategies, it would be most appropriate to calculate a ... 1) independent-samples t 2) one sample t 3) paired samples t 4) z test
Why is it important to report both a measure of central tendency and variability to describe a set of scores? Group of answer choices Sets of data with different central tendencies may have different patterns of variability. Sets of data with the same central tendency may have the same patterns of variability. Sets of data with the same variability may have different patterns of central tendency. Sets of data with the same central tendency may have different patterns of variability.

Consider the following data. Satisfaction level depended on the speed of execution. A portion of the survey results are as follows: Brokerage Satisfaction Speed Scottrade, Inc. 3.5 3.4 Charles Schwab 3.4 3.3 Fidelity Brokerage Services 3.9 3.4 TD Ameritrade 3.7 3.6 USAA Brokerage Services 2.9 3.22 | Page Vanguard Brokerage Services 2.6 2.6 Wells Fargo Investments 4.0 4.0 i. At the ��= 0.01 level, would you feel comfortable to use the estimated regression equation to relate the speed of execution and satisfaction level? What is your conclusion? (Use p-vale approach) ii. Estimate the 98% confidence interval for speed of execution

The mean birthweight of an infant is thought to be associated with the smoking status of the mother during the first trimester of the pregnancy. Consider the following data from mothers divided into four categories according to smoking habits, and the corresponding birthweights of their children. Group 1: Mother is a non smoker (NON): 7.5, 6.2, 6.9, 7.4, 9.2, 8.3, 7.6 Group 2: Mother is an ex-smoker (EX): 5.8, 7.3, 8.2, 7.1, 7.8 Group 3: Mother is a current smoker, smokes less than 1 pack per day (CUR < 1) 5.9, 6.2, 5.8, 4.7, 8.3, 7.2, 6.2 Group 4: Mother is a current smoker, smokes more than or equal to 1 pack per day (Cur ≥ 1) 6.2, 6.8, 5.7, 4.9, 6.2, 7.1, 5.8, 5.4 Using Stata test whether or not the mean birthweights are equal across all four groups at the alpha = 0.05 level.

You are a manager for Company ABC and decide to compile data and analyze your employees’ level of satisifaction. You create a survey to ask each employee to rate their level of satisfaction working at Company ABC. Table 1 shows data of 15 people employees that responded to your survey. Each of the employees have the same job title: Sales Representative. The data set includes variables regarding an employee ID, gender, ethnicity, region, pay rate, employee satisfaction rating. Each employee was asked to rate their level of satisfaction working at Company ABC. A composite score from 0 (lowest) to 5 (highest) is shown as the data variable employee satisfaction.
