First Order Inclusion Probabilities Survey Questions
Every sample of size 6 has equal chance (randomly choose 6 students out of 30). Answer following questions: (a)
How many possible samples?(b) p(s) = ?(c)
ns = ?(d) Number of sample containing unit k?(e)
First order inclusion probabilities?(f)
Second order inclusion probabilitiesIf the design has a fixed sample size n, then pi ik> pi i +pi k -1 Give a brief example of surveys with the following properties. You should identify and define enough of the population, sampling frame, sample design and data collection to be convinving in your answers. The survey is not a probability sample. The survey is a probability sample but does not have a measurable design AND is not a systematic sample (SY). The survey is a probability sample with a measuable design, but there is likely to be a problem with some other aspect of the survey (e.g., non response or response error).The survey has a great design, but is simply impractical due to cost and/or time constraints.4. 2.6 from SSW (Särndal, Swensson, Wretman) 5. using the given data to running R code
As an exercise, we
will estimate the population of Iowa in the year 2000 based on a sample of
counties.

a.Make a two-way table that includes the marginal frequencies.
b.Make a two-way table that shows both the joint and marginal relative frequencies. Round to the nearest hundredth, if necessary.
c.What is the probability that someone who is between the ages of 20-29 also texts regularly?
d.What is the probability that someone who is between the ages of 40-49 also texts regularly?
e.Does the data show a relationship between age and texting? Explain.
2. The data below represents the number of hits on your web site over 10 months.
a.Make a scatter plot of ln y versus x. Use the scatter plot to find the equation for the line of best fit.
b.Make a scatter plot of ln y versus ln x. Use the scatter plot to find the equation for the line of best fit.
c.Based on your answers in part a and b, would an exponential model or a power model be better to represent this data? Explain.
d.Use your answers from parts a and b to find an exponential model and a power model to represent this data by hand.
e.Use the regression feature on your calculator to find an exponential model and a power model to represent this data.
f.Use your answer from parts c and d to make the best estimate for the number of hits your web site will have in 12 months.

Business Analytics
In this assignment, you will be assessed based on the following outcome: GB513-3: Predict business results by using quantitative methods. Make sure to use the Unit 4 Assignment template to turn in your answers. This assignment requires you to use Excel in all three questions. Make sure you explain your answers and provide the regression output tables for Questions 1 and 2 as you are showing work in the template (see attached). You still need to submit the Excel file you used to generate your answers, in addition to the report in Word. Failure to submit the Excel file will result in a 20 point deduction.Question 1 Shown below are rental and leasing revenue figures for office machinery and equipment in the United States over a 7-year period according to the U.S. Census Bureau. Use this data and the regression tool in the data analysis tool pack to run a linear regression. Based on the formula you get from the regression output, answer the following questions: a)What is the forecast for the rental and leasing revenue for the year 2011? b)How confident are you in this forecast? Explain your answer by citing the relevant metrics. Do not just put down a number without explanation.Year Rental and Leasing ($ millions) 2004 5,8602005 6,6322006 6,5432007 5,9522008 5,7322009 5,4232010 4,589Question 2 Suppose a researcher gathered survey data from 19 employees and asked the employees to rate their job satisfaction on a scale from 0 to 100 (with 100 being perfectly satisfied). Suppose the following data represent the results of this survey. Assume that relationship with their supervisor is rated on a scale from 0 to 50 (0 represents a poor relationship and 50 represents an excellent relationship); overall quality of the work environment is rated on a scale from 0 to 100 (0 represents poor work environment and 100 represents an excellent work environment); and opportunities for advancement is rated on a scale from 0 to 100 (0 represents no opportunities and 100 represents excellent opportunities). Answer the following questions: a)What is the regression formula based on the results from your regression? b)How reliable do you think the estimates will be based on this formula? Explain your answer by citing the relevant metrics. Do not just put down a number without explanation.c)Are there any variables that do not appear to be good predictors of job satisfaction? How can you tell? d)If a new employee reports that her relationship with her supervisor is 40, rates her opportunities for advancement to be at 30, finds the quality of the work environment to be at 75, and works 60 hours per week, what would you expect her job satisfaction score to be?
