Rao Technologies, a California-based high-tech manufacturer, is considering outsourcing some of its electronics production. Four firms have responded to its request for bids, and CEO Mohan Rao has started to perform an analysis on the scores his team has entered in the table below.
|| | | RATINGS OF OUTSOURCE PROVIDERS || | | | :--- | ---: | ---: | ---: | ---: | ---: | | FACTOR | WEIGHT | A | B | C | D | | Labor | W | | | | | | Quality procedures | | | | | | | Logistics system | | | | | | | Price | | | | | | | Trustworthiness | | | | | | | Technology in place | | | | | | | Management team | | | | | |
Weights are on a scale from 1 through 30 , and the outsourcing provider scores are on a scale of 1 through 5 . The weight for the labor factor is shown as a w because Rao's team cannot agree on a value for this weight. For what range of values of , if any, is company a recommended outsourcing provider, according to the factor-rating method?
A hospital emergency room analyzed n = 17,664 hourly observations on its average occupancy rates using six binary predictors representing days of the week and two binary predictors rep- resenting the 8-hour work shift (12 a.m.–8 a.m., 8 a.m.–4 p.m., 4 p.m.–12 a.m.) when the ER census was taken. The fitted regression equation was AvgOccupancy = 11.2 + 1.19 Mon - 0.187 Tue - 0.785 Wed - 0.580 Thu - 0.451 Fri - 0.267 Sat - 4.58 Shift1 - 1.65 Shift2 (SE = 6.18, = .094, = .093).
Assess the regression’s fit.
Assume that you write a column for a very widely followed financial blog titled “Finance Questions: Ask the Expert.” Your job is to field readers’ questions that deal with finance. This week you are going to address two questions from your readers that have to do with dividends.
Question 2: I’m on the board of directors of the B. Phillips Corporation, and Phillips has announced its plan to pay dividends of $550,000. Presently, there are 275,000 shares outstanding, and the earnings per share is$6. It looks like the stock should sell for $45 after the ex-dividend date. If instead of paying a dividend, the management has decided to repurchase stock,
- a. What should be the repurchase price that is equivalent to the proposed dividend? (Hint: Ignore any tax effects.)
- b. How many shares should the company repurchase?
- c. You want to look out for the small shareholders. If someone owns 100 shares, do you think she would prefer that the company pay the dividend or repurchase stock?
