- An Employee Value Proposition (EVP) is about defining the essence of a company. The EVP is the value an employee receives from the employer; it defines the commitment the company will make to develop the employee in exchange for the effort the employee puts in to benefit the company. But do all agree on what makes a unique and compelling EVP? A study showed that 14% of business executives, 36% of HR leaders, and 31% of employees say that compensation (pay and rewards) makes for a unique and compelling EVP. Assume that 200 individuals within each business group were surveyed. Complete parts (a) through (c). State the null and alternative hypotheses. Use a=0.05 The test statistic is x^2stat= The critical value = b. Determine the p-value and interpret its meaning.An Investec analyst is looking to invest R180,000 in hopes of getting the highest return possible. There are four investment options available: bonds, mutual funds, stocks, or a savings account yielding interest. The bonds give a 4% annual return, mutual funds give an 9% return, stocks give a 12% return, and the savings account gives a 3% return with all investments being subject to risk. To control for risk, the following constraints are put into place: a) No more than 12% of the total investment can be put into stocks. b) At most 30% must be invested in mutual funds and/or the savings account. c) The amount put in the bonds must be no more than the amount put into the other investments combined. d) The ratio of money invested in mutual funds to the amount invested in stocks and the savings account should be at least 2 to 1. e) All the R180,000 must be invested and no shorting is allowed. Formulate a linear programming model for this problem to get the highest return (i.e., Define…Ital all U| * Starred 3.

- Types of Compensation People don't work for free, and how much employees are paid for their work is a complicated issue. Also, designing a fair compensation plan is an important task because pay and benefits represent a substantial portion of an organization's expenses. Wages that are too high may result in the company's products being priced too high, making them uncompetitive in the market. Wages that are too low may damage employee morale and result in costly turnover. Financial compensation falls into two categories: wages and salaries. Additionally, there are three common types of financial incentives: commission, bonuses, and profit sharing. Read the statements describing compensation attributes and the various employee examples and select the most appropriate form of compensation each describes. 1.Paid by the Hour-Employees receive these financial rewards in return for the number of hours they have worked.

During this time, Westminster provided a choice among 12 pre-designed investment packages. The investment packages were classified according to two variables: riskiness of investment package chosen ("Risky", "Moderate/mixed", and "Conservative") and age of investor ("Under 35", "35-49", or "50+"). Suppose that we're interested in the possible relationship between the age of the investor and the riskiness of the investment package the investor chose. The following contingency table gives a summary of the information released by Westminster regarding age and riskiness of investment package for 150 investors. In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, riskiness of investment package chosen and age of investor, are independent. Round…
- Exercise 2. Marginal and Conditional Relationships can be Very Different. For 100 mild cases of eczema, a new treatment had a higher cure rate than the old treatment (33.3% of 90 vs. 20% of 10). For 100 severe cases of eczema, again the new treatment had a higher cure rate than the old treatment (60% of 20 vs. 50% of 80). Over all 200 eczema cases, however, the old treatment had a higher cure rate than the new treatment- i.e. Simpson's Paradox strikes again. (a) Compute the overall cure rates for the new and old treatments. (b) Which treatment, old or new, would you choose and why?please show all your steps (including decision trees)
