Scenario#1

Answer all questions

1. Describe how the social and physical environment can support health promoting behaviour. What areas are inconsistent with health promoting behaviours?

2. You recently studied the Stage of Change Model and are interested in applying it to a wellness program. Following a discussion with Debra, it was decided that she needs to incorporate more physical activity in her daily life.

a.   In the development of a wellness plan, show how you might apply the Stages of Change Model for Debra. Identify the goal for teaching intervention for each stage.

3. a. Identify a clinical situation or personal experience with someone whose functioning or quality of life is limited by illness.                                                             

b. Explore internet resources to find technology- based interventions that the person could use to improve his or her wellness                                                                  

5. Jamestown Furniture Co. is a small, but fast-growing manufacturer of living room furniture. Its two principal products are end tables and sofas. There are five processes in the manufacturing at Jamestown: Cutting the lumber, cutting the fabric, sanding, staining, and assembly. Jamestown has one employee working in fabric cutting and one employee working in staining. These are relatively skilled workers and could be replaced only with some difficulty. The cutting and sanding operations are performed by two workers each, and while there is some skill to these operations, it is less critical than for staining and for fabric cutting. Assembly is the least skill-based process and is currently done by one full-time employee and a group of part timers who provide a total of 175 minutes of working time per week. The other employees work a 40-hour week, with 5 hours off for breaks, training, and personal time. Assume a fourweek month, and that by prior agreement, any of the employees can be switched from one task to another.

The current demand for Jamestown's products and sales prices are provided below. Jamestown expects demand to increase significantly in the coming months (this depends on whether it is able to successfully obtain the order it is negotiating to get from a motel chain). The materials cost for the table is $150 and $275 for the sofa.

The time required for each activity and the total time available are shown below.

A travel analyst claims that the standard deviation of the room rates for two adults at 3-star hotels in Denver, Colorado is more than $68. A random sample of 18 3-star hotels has a standard deviation of $40. Use a 0.10 significance level to test the analyst’s claim. Assume the population is normally distributed.

e. Conclusion (step 8):

A company is attempting to select between two financing alternatives. Option 1 is to issue an       additional $1 million in debt at 8%. The second option is to issue $1 million o common shares at $25/share. The firm currently has $250,000 of 7% debt and 100,000 shares of common outstanding. Its tax rate is 40%.

a. What is the indifference point?

b. Which option would you choose if the EBIT is projected to be $100,000?

c. Which option would you choose if the EBIT is projected to be $350,000?

The W.C. Pruett Corp. has $250,000 of interest-bearing debt outstanding, and it pays an annual interest rate of 8%. In addition, it has $600,000 of common stock on its balance sheet. It finances with only debt and common equity, so it has no preferred stock. Its annual sales are $1.6 million, its average tax rate is 40%, and its profit margin is 7%. What are its TIE ratio and its return on invested capital (ROIC)? Round your answers to two decimal places.

. Consider the following sorting procedure. This procedure uses nested loops to make several passes through the array. Each pass compares successive pairs of elements. If a pair is in increasing order (or the values are equal), the sorting procedure leaves the values as they are. If a pair is in decreasing order, the sorting procedure swaps their values in the array.  The first pass compares the first two elements of the array and swaps their values if necessary.  It then compares the second and third elements in the array.  The end of this pass compares the last two elements in the array and swaps them if necessary.  After one pass, the largest element will be in the last index.  After two passes, the largest two elements will be in the last two indices.  After n – 1 pases (where n is the size of the array), the largest n – 1 elements will be in the last n – 1 indices and we have a sorted array.(java

Consider the following data for two variables, x and y.

(a)

Compute the standardized residuals for these data. (Round your answers to two decimal places.)

Do the data include any outliers? Explain. (Round your answers to two decimal places.)

The standardized residual with the largest absolute value is  , corresponding to y_i =  . Since this residual is  ---Select--- less than −2 between −2 and +2 greater than +2 , it  ---Select--- is definitely not could be an outlier.

(b)

Plot the standardized residuals against ŷ.

A standardized residual plot has 7 points plotted on it. The horizontal axis ranges from 105 to 140 and is labeled: y hat. The vertical axis ranges from −2.5 to 2.5 and is labeled: Standardized Residuals. There is a horizontal line that spans the graph at 0 on the vertical axis. There are 4 points below the line and 3 points above it. 6 of the points appear to vary randomly between −0.8 to 0.1 on the vertical axis; however, the maximum residual is at approximately (121, 2.2).

Does the scatter diagram indicate any outliers in the data?

The diagram indicates that there are no possible outliers.The diagram indicates that there is one possible outlier.    The diagram indicates that there are two possible outliers.The diagram indicates that there are more than two possible outliers.

In general, what implications does this finding have for simple linear regression?

For simple linear regression, we must calculate standardized residuals, plot a standardized residual plot, and construct a scatter diagram to identify an outlier.For simple linear regression, we can determine an outlier by looking at the scatter diagram.     For simple linear regression, it is impossible to determine whether there is an outlier using standardized residuals, a standardized residual plot, or a scatter diagram.
