Stat 2002 Walden University Confidence Intervals in Political Polls Discussion
PROMPT:One of the most common uses of confidence intervals is found in political polls and the news articles that reference them. These articles often use the point estimate (the proportion), and you can usually find the margin of error (half of the confidence interval) somewhere in the article as well. For example, consider the following scenario:Two separate polling organizations have conducted polls for two candidates who are running for state senate, Gail Schultz and Raymond McGregor. The polls were taken from the same population, in the same state, and on the same day. The survey from the first company, Pollster Analytics, shows Gail having 49% of the potential vote. It also shows Raymond having an estimated 47% of likely voters. Both results reflect a margin of error of 2 percentage points (usually depicted as ±2%).The survey from the second company, Polltastik, shows Raymond at 49% and Gail at 46%. This survey has a 3-percentage-point margin of error (±3%).In this Discussion, you will compare the outcomes of the surveys in the scenario and apply the concept of confidence intervals to make a prediction for the upcoming election, as well as discuss their implications. Assignment (Refer to the scenario described above and consider who is ahead in the race and why)Post a 75- to 150-word (1- to 2-paragraph) explanation of how you applied confidence intervals to make predictions about the outcome of a political campaign. In your explanation, address the following:After reviewing both polls, what is now known about who might be ahead in the race? Explain who is ahead and why.Explain what the implications of these polls are for the campaign managers for Gail and Raymond.To support your response, be sure to reference at least one properly cited scholarly source.

Central Ohio Technical College Data Driven Decision Making Questions
Please solve the hypothesis testing problems (#1, and 2) using Minitab as the tool. For each problem, (1) specify the business and statistical hypotheses, (2) specify what the Type I and Type II errors are in this business context, and, the implications of making those errors, (3) include the results from Minitab, (4) draw appropriate conclusions to your statistical hypotheses based on the results, and, finally, (5) present the business conclusions in a short non-statistical summary. For problem 3, use Minitab and follow instructions given with the problem. For problem 4, several analyses will be necessary. Present each analysis with business/statistical hypotheses, Minitab results, and business conclusions. Incorporate those analyses into a short report.
Suppose Smith and Wilson is a relatively small West Coast advertising agency. Assume that they have hired you to help in their newly established advertising research department. Your first task is to evaluate the results of a copy test for a new consumer product. Three different versions of the advertisement were prepared. A random sample of 10 viewers watched the three versions. After each commercial was shown, each consumer’s attitude toward the product was measured on a scale of 1 to 100 (the higher the score, the more favorable the attitude). The scores of the 10 viewers are below:

After receiving your bachelor’s degree in personnel management, you were hired by a small but expanding life insurance company. Your first assignment is to develop a more efficient technique for the preliminary screening of applicants for sales positions. Since the firm employs only college graduates, you decide to work with information focusing on their performance during college.
A random sample of 25 from the firm’s current sales force is selected and the following information is obtained:
Last year’s performance evaluation score
College grade point average (GPA)
Percent of total college expenses earned by the individual
Number of social organizations the individual belonged to

On the basis of the data obtained, what recommendations can you make regarding the preliminary screening of applicants for sales positions?
3. A contractor has recorded the number of jobs performed in the last seven months.
a.Draw a graph of the number of jobs (as y) and time (as x). Be sure to label the axes.
For each of the following methods, develop a forecast for the number of jobs for the 8th month.
b.A three-period moving average
c.Exponential smoothing (use Minitab default smoothing parameters)
d.A linear trend equation
Using the mean squared difference (MSD), explain which of the methods you believe results in the best forecast and make your recommendation to the contractor about what he should expect for the eighth month.
