Do questions E-H

Feeding behavior of black bream fish. In Brain and Behavior Evolution (April 2000), Zoologists conducted a study of the feeding behavior of black bream fish. The zoologists recorded the number of aggressive strikes of two black bream fish feeding at the bottom of an aquarium in the 10-minute period following the addition of food. The next table lists the weekly number of strikes and age of the fish (in days).

Week ? ? ? ? ? ? ? ? ?

Number of Strikes ?? ?? ?? ?? ?? ?? ?? ?? ??

Age of Fish (days) ??? ??? ??? ??? ??? ??? ??? ??? ???

We want to fit a straight-line model relating number of strikes(y) to age of fish (x).

a. Find ???? , ???? ??? ???? .

b. Find the least squares estimators ?̂ 0 and ?̂ 1 and give the least squares prediction equation.

c. Give a practical interpretation of the value of ?̂ 1.

d. Find ? 2 , the estimator of the variance ? 2 of the random error term ?.

e. Use the least squares model to estimate the mean number of strikes if the age of fish is 170 days.

f. List the assumptions required for the regression analysis.

g. Is there evidence that age of fish contributes information for the prediction of number of strikes? Conduct a hypothesis test using ? = 0.1.

h. Find a 97 % Confidence interval for ?1.

For the number of daily calories consumed and life satisfaction report the z-scores for participants number 2,6 and 7 . Discuss where these participants scored in relation to the mean and explain how you know the information.

Calculate what raw score was equal to a z score of -1

Using the z table explain what percentage of the distribution scored below this score

Calculate z-scores for these participants 2,6,7 using the z-score formula

Rearrange the formula to figure out what raw scores corresponds with a Z-SORE OF -1

The pre-2000’s-style television sets were based on cathode ray tube (CRT) technology. A CRT is a vacuum tube that operates by heating an internal metal filament (the cathode) to a high temperature so that electrons are ejected from its surface. These electrons are then accelerated through a large voltage towards the positively charged anode before striking a phosphor-coated screen to produce visible light. Assume that the electrons start from rest and are accelerated across a voltage difference of 1000~V1000 V. Calculate the speed of the electron when it strikes the phosphor-coated screen.

Suppose we have data from a health survey conducted in year 2000. Data were obtained from a random sample of 1000 persons.

An OLS linear regression analysis was carried out in the following way:

Dependent Variable: Systolic blood pressure (SBP, in mmHg)

Independent Variables: Gender (1 if female, 0 if male)

Age (in years)

Education (binary variables for “Not graduated from high school” and “Graduated from high school (but not from college)”; the reference category is “Graduated from college”)

A part of the results is shown below. The column labeled “Beta” show estimated values of partial regression coefficients. (It can be interpreted that beta’s for the reference categories, “Male” and “Graduated from college”, are fixed to be zero.) The p-values are for the two-sided test.

1. According to the results of this regression analysis, how much expected difference in systolic blood pressure (in mmHg) is estimated:

1-1. between the two education categories, “Not graduated from high school” and “Graduated from college”, controlling for gender and age (i.e., among those who have the same gender and at the same age)?

1-2. between males and females, controlling for age and education?

2. Suppose we change the reference category of education from “Graduated from college” to “Graduated from high school” and do the same regression analysis again.

What will be the value of partial regression coefficient (beta) for “Not graduated from high school”?

(Hint: The expected SBP differences among the education categories do not change.)

$20000 for the cost of labor in the factory
$54000 for the depreciation on administrative equipment
$140000 for depreciation on the manufacturing equipment

Deuce had no inventory on hand at the beginning of Year3. The company sold 800 engines during Year3.

Round your final answers to the nearest dollar, if needed. Do not include any commas or other punctuation in your answer.

Do not enter expenses as a negative number.

Strategic Management: A Taiwanese story about strategy and structure Before 2000 the Taiwan-based company Acer had competing strategies. For 15 years one part of the firm had been building computers for other PC sellers who would put their own labels on the machines, while another part sold very similar computers under the company’s own brand. The latter strategy was predicated on direct sales to consumers, which had brought the firm into direct competition with companies such as Dell. However, in 2000 the firm decided to adopt a new business strategy in order to increase its global market share. Acer’s manufacturing division was made an independent company (Wistron) and this enabled a smaller and more nimble sales firm to emerge. The strategy based on direct sales was discarded and replaced with a strategy focused on selling as many low-cost laptops and netbooks as possible to consumers but via a network of partners and retailers. A new logo was adopted to reflect this new strategic direction, which had proved very successful despite the industry downturn. By 2008, Acer had replaced Hewlett-Packard as the market leader in Europe, the Middle-East, and Africa, partly as a result of Acer’s success in the booming netbook market. This strategy enabled the firm to become the world’s second largest PC vendor. However, in 2011 tensions at board level over the firm’s strategic direction culminated in the resignation of Acer’s CEO Gianfranco Lanci. The difference in opinion appears to be about whether the firm’s future lay in PC’s or mobile devices. Acting CEO J.T Wang announced that the PC would continue to be the firm’s core business. In 2009 the firm entered the smartphone market with the launch of four different smartphones and the promise of more in the pipeline. Unlike Apple, which was focused on developing one phone only, Acer’s strategy is based on targeting each of its phones at a different market segment. In march MODULE FUNDAMENTALS OF HUMAN RESOURCE MANAGEMENT TOTAL MARKS 60 MARKS 2011, Acer announced that revenue projections for the first quarter in 2011 will fall short of expectations by about 10% due to weaker demand in the PC market in the US and Europe.
