A company recently announced that the performance of employees would be rated on a scale from 1 to 4. The top 10%of employees would receive a1 rating, 15% of the employees would be rated with a 2, and 55%would be rated with a 3. The remaining employees would receive a 4 rating. The rating scheme is known as a forced-ranking system. It was begun after the government bailed out the company and forced the company to link compensation to performance. Suppose that one facility of the company has 350 employees. Determine the number of employees who can receive each rating. employees can receive a rating of 1.----employees can receive a rating of 2.---- employees can receive a rating of 3.---- employees can receive a rating of 4.----
Group I nesting boxes were well separated from each other and well hidden by availablebrush. There were a total of 480 eggs in group I, of which a field count showed about275 hatched. Group II nesting boxes were placed in highly visible locations and groupedclosely together. There were a total of 874 eggs in group II boxes, of which a field countshowed about 272 hatched. Find a point estimate ˆp1 and ˆp2 for the proportion of eggsthat hatch in group I nest boxes and group II nest boxes. Let p1 and p2 be the populationproportion of hatched count in boxes I and II respectively. Find a 99% confidence intervalfor p1 − p2.(a) List the given information with appropriate symbols.(b) What is the probability distribution of ˆp1−pˆ2, difference between sample proportions?(c) Write the expression for the population mean of ˆp1 − pˆ2 distribution.

The trend in home building in recent years has been to emphasize open spaces and great rooms, rather than smaller living rooms and family rooms. A builder of speculative homes in the college community of Oxford, Ohio, had been building such homes, but his homes had been taking many months to sell and had been selling for substantially less than the asking price. In order to determine what types of homes would attract residents of the community, the builder contacted a statistician at a local college. The statistician went to a local real estate agency and obtained the data contained in file OxHome. This data includes the sales price (measured in thousand dollars), square footage, number of rooms, number of bedrooms, and age for each of 60 single-family residences recently sold in the community. Using this data, a regression model was built to predict the sales price of houses in this community. The regression equation from the model is: sales price (thousand dollars) = 19.5 + 0.1079…

The Royal Seas Company runs a three-night cruise to the Caribbean from Port Canaveral. The company wants to run TV ads promoting its cruises to high-income men, high-income women, and retirees. The company has decided to consider airing ads during prime time, afternoon soap operas, and during the evening news. The number of exposures (in millions) expected to be generated by each type of ad in each of the company's target audiences is summarized in the following table: Prime Time Soap Operas Evening News High-income men 6 3 6 High-income women 3 4 4 Retirees 4 7 3 Ads during prime time, the afternoon soaps, and the news hour cost $120,000, $85,000, and $100,000, respectively. Royal Seas wants to achieve the following goals: Goal 1: Spend approximately $900,000 on TV advertising. Goal 2: Generate approximately 45 million exposures among high-income men. Goal 3: Generate approximately 65 million exposures among high-income women. Goal 4: Generate approximately 60 million…
Suppose Ted is creating a football team in a video game that features many NFL players. He decides to identify players who are outliers in a few statistics he has chosen. Currently, he's looking at wide receivers. The game includes the top 100 receivers in 2012 by number of receptions. Ted, however, is more interested in receiving yards, and the table shows the five-number summary of the available players in the game (in yards): Minimum 1st quartile (Q1) Median 3rd quartile (Q3) Maximum 258.0 549.5 743.0 936.5 1964.0 The mean is 787.6 yds with a standard deviation of 311.3 yds. Ted first calculates the interquartile range (IQR). Next, to determine suspected outliers, he calculates Q1−1.5⋅???Q1−1.5⋅IQR and Q3+1.5⋅???Q3+1.5⋅IQR. Specify those results to at least one decimal place. Q1−1.5⋅???Q1−1.5⋅IQR = Q3+1.5⋅???Q3+1.5⋅IQR =
