An auditor for a hardware store chain wished to compare the efficiency of two different auditing techniques. To do this he selected a sample of nine store accounts and applied auditingtechniques A and B to each of the nine accounts selected. The number of errors found in each of techniques A and B is listed in the table below:Errors in A Errors in B453137483946483754525045494941405045Does the data provide sufficient evidence to conclude that the number of errors in auditing technique A is greater than the number of errors in auditing technique B at the 0.01 level ofsignificance?

A local West Lafayette commercial bank issues Mastercard credit cards. As a part of its annual review of the profitability of each type of credit card, the bank randomly samples 36 customers to measure the average annual charges per card. A random sample of 36 Mastercard accounts shows the following annual spending per account (in USD): 2869 3770 2854 2750 2574 2972 2549 3267 3013 2707 2794 1189 2230 2178 3032 3485 2679 2010 1994 2768 3853 2064 3244 2738 2807 2395 3405 3006 3368 2691 1996 3008 2518 2674 2730 3719 1. Based on these randomly sampled accounts, what is the best point estimate of the true mean annual spending for Mastercard account holders? 2. Develop a 95% confidence interval estimate of the mean annual spending. Interpret this range. 3. To encourage more use of the card, the company offers a promotion that costs the bank $5 for each card that carries a balance of $3,000 or more. If the bank has 50,000 total customers, what can be stated about the cost of this…
A visiting comparative literature student from Cambridge University believes that contemporary readers prefer novels from George RR Martin (the author of the Games of Thrones saga) to Shakespeare. She devises a study in which 40 participants are asked to read excerpts from both Shakespeare plays and Games of Thrones books and rate their level of satisfaction for each excerpt. Satisfaction is measured using a 5-point Likert scale (5 indicates high satisfaction). In order to allow for a fair comparison, she hides the name of the authors and recruits a professional translator to adapt the Games of Thrones text to old Elizabethan English. The order of presentation is also randomised and balanced across participants. The attached CSV file contains the data that was collected for the experiment. What can you conclude from the results of this experiment? I require assistance on: Identifying the appropriate statistical test. Conducting the statistical test in JASP, Excel or SPSS. Reporting…
Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours). B, C, and D
An experiment to determine the most effective way to teach safety principles applied four different teaching methods. Some employees were given programmed instruction booklets and worked through the course at their own pace. Other employees attended lectures. A third group watched a television presentation, and a fourth group was divided into small discussion groups. A high of 10 was possible. A sample of five tests was selected from each group. The test grade results were: Sample Number Programmed Instruction Lecture TV Group Discussion 1 6 8 7 8 2 7 5 9 5 3 6 8 6 6 4 5 6 8 6 5 6 8 5 5 At the 0.01 level, what is the critical value?

When an audit must be conducted that involves a tedious examination of a large inventory, the audit may be very costly and time consuming if each item in the inventory must be examined. In such situations, the auditor frequently obtains a random sample of items from the complete inventory and uses the results of an audit of the sampled items to check the validity of the company's financial statement. A large company’s financial statement claims an inventory that averages $600 per item. The following data are the auditor’s assessment of a random sample of 75 items from the company’s inventory. The values resulting from the audit are rounded to the nearest dollar. Estimate the mean value of an item in the inventory using a 95% confidence interval. Is there substantial evidence (a 5 .01) that the mean value of an item in the inventory is less than $600? What is the target population for the above inferences? Would normal distribution–based procedures be appropriate for answering the…
Consider the following research questions/study scenarios. For each study, discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be most appropriate for addressing the research questions? Be sure to provide a justification of the statistical method. What statistical test is needed, provide appropriate null and research hypotheses. An investigation of the association between drink preferences and the color of teeth is proposed. Subjects will be surveyed as to the type of drink most often consumed (coffee/tea. Juice, caramel-colored soda, water, or milk). A clinical exam will be performed after dental cleaning to determine the color of the teeth (reddish brown, reddish yellow, gray, reddish gray).
