...Week 6 Course Project B) Written below is a sample communication via the use of a memorandum George Fisher has sent out to his employees at Kodak. In this communication message it will give information about the change Kodak is making into the digital world. Memorandum To: All Staff From: Mr. George Fisher, CEO Date: January 12, 2002 Subject: Changes to come For the past ten years we have been designing a strategy to embark on a new change into the digital world, leaving behind the existence of the use of film. It is crucial that we stay above our competitors and continue to change and explore new ways of finding our way in staying competitive in this ever-changing market. That is why we are beginning our conversion from film to digital imaging in the weeks to come. We will launch the changes immediately to in order to get our production started as our estimates are growth show much potential for success. Now, we might face some obstacles along the way in executing the change. Such as the need to invest in research and “release incrementally updated products in a number of different fields” as soon as possible, but we believe this will work. Therefore, we need you on board because you are the essential factor in helping us making this change a success story, and a great moment in Kodak’s history. We might have to cut some of our losses along the way, such as factories and jobs, in order to keep up with our counterparts and competitors, but there is more......

...Project Part B: Hypothesis Testing and Confidence Intervals a. The average (mean) annual income was less than $50,000 Null Hypothesis: The average annual income was greater than or equal to $50,000 H₀: µ > 50000 Alternate Hypothesis: The average annual income was less than $50,000. Ha: µ > 50000 Analysis Plan: Significance Level, α=0.05. Since the sample size, n > 30 I will use z-test for mean to test the given hypothesis. As the alternative hypothesis is Ha: µ > 50000, the given test is a one-tailed z-test. Critical Value and Decision Rule: The critical value for significance level, α=0.05 for a lower-tailed z-test is given as-1.645. Decision Rule: Reject H₀, if z – statistic, -1.645 Test Statistic - minitab One-Sample Z: Income ($1000) Test of mu = 50 vs < 50 The assumed standard deviation = 14.55 95% Upper Variable N Mean StDev SE Mean Bound Z P Income ($1000) 50 43.48 14.55 2.06 46.86 -3.17 0.001 Interpretation of Results and Conclusion: Since the P-value (0.0001) is smaller than the significance level (0.05), we reject the null hypothesis. The p-value implies the probability of rejecting a true null hypothesis.

...Project Part B: Hypothesis Testing and Confidence Intervals | | Your manager has speculated the following: a. the average (mean) annual income was less than $50,000, b. the true population proportion of customers who live in an urban area exceeds 40%, c. the average (mean) number of years lived in the current home is less than 13 years, d. the average (mean) credit balance for suburban customers is more than $4300. 1. Using the sample data, perform the hypothesis test for each of the above situations in order to see if there is evidence to support your manager’s belief in each case a.-d. In each case use the Seven Elements of a Test of Hypothesis, in Section 6.2 of your text book with α = .05, and explain your conclusion in simple terms. Also be sure to compute the p-value and interpret. 2. Follow this up with computing 95% confidence intervals for each of the variables described in a.-d., and again interpreting these intervals. 3. Write a report to your manager about the results, distilling down the results in a way that would be understandable to someone who does not know statistics. Clear explanations and interpretations are critical. Project Part B: Hypothesis Testing and Confidence Intervals a.

...Maurice S. Butler Math533—Applied Managerial Statistics Course Project: Part A Introduction This project is based upon statistical data compiled concerning AJ Davis Department Stores, specific to a sample of its customer base. It is with intent of establishing relationship between location, gross income, and credit balances carried by customers that the following statistical analysis has been performed. It is assumed that information obtained as well as the interpretation of statistical analysis will enable credible recommendations in regard to future revenues or continued handling and/or maintenance of its receivables. Variables The first variable is the gross income of the stores’ customers. The data set includes 50 customers with gross income ranging from $20,000 to $79,000 per year. Compilation of the data into a frequency/relative frequency table (see below) reveals that the greatest frequency and relative frequency of the store’s customers is found within the $30,000 to $49,000 range. Fifty-two percent of the store’s customer base gross income is found within this range. First and third quartiles have been calculated to be 33 and 57 respectfully. However, no outliers have been identified within the data set. Income ($1000) | Frequency | Relative Frequency | 20-29 | 5 | 10% | 30-39 | 13 | 26% | 40-49 | 13 | 26% | 50-59 | 8 | 16% | 60-69 | 9 | 18% | 70-79 | 2 | 4% | | 50 | 100% | My second variable is the outstanding credit balances of...

...Keller graduate school of management | Department Store part B | Week 6 project for AJ Davis | Information from the project for AJ Davis department store. Attached in this report is all information related to the information listed from Excel. | Results from Minitab findings The mean income was less than $50,000. The Null Hypothesis: which states the average annual income was greater than or equal to 50. The number of trials (n) is larger than 30 use ztest to check the hypothesis. With the Critical Value and decision rule: Reject H0 if Z –value is -1.645. By using the z-test the one sample z: results are as follows: z -3.02 p .001 mean 43.74. The p value .999 is larger than .05, so I would not reject the null hypothesis. The p value shows the probability of rejecting null hypothesis. The confidence level of .05 shows there is enough data to support the claim that the average annual income was less than $50,000. The confidence level at 99.5% is 38.41 and since 50 are above the 99.5% confidence level shows support for the claim that the mean income is less than $50,000. The proportion of customers who live in urban areas exceeds 40%. For this 21 out of the 50 people in the data live in an urban area. This equates to .42 so my point estimate would be .42 or 42%. The Ho: p=.40 vs. Ha: p >.40. z= .29. The reject area is z> 1.645; since .29 is less than 1.645 I would not reject Ho. The p value is .386. By not rejecting this is saying there is......
