. About 5% of a store’s customers respond to advertised sales. The other 95% shop when they have time or because they need an item, regardless of promotional advertising. Of the 21 customers randomly selected in the shop, calculate the following questions: d) Calculate the average number of customers responding to the advertisement (rounded off to two decimals). e) Calculating the variance of customers responding to the advertisement (rounded off to four decimals).

A contributor for the local newspaper is writing an article for the weekly fitness section. To prepare for the story, she conducts a study to compare the exercise habits of people who exercise in the morning to the exercise habits of people who work out in the afternoon or evening. She selects three different health centers from which to draw her samples. The 57 people she sampled who work out in the morning have a mean of 4.8 hours of exercise each week. The 56 people surveyed who exercise in the afternoon or evening have a mean of 4.2 hours of exercise each week. Assume that the weekly exercise times have a population standard deviation of 0.8 hours for people who exercise in the morning and 0.3 hours for people who exercise in the afternoon or evening. Let Population 1 be people who exercise in the morning and Population 2 be people who exercise in the afternoon or evening. Step 1 of 2 : Construct a 95% confidence interval for the true difference between the mean amounts…

A J.D. Power and Associates vehicle quality survey asked new owners a variety of questions about their recently purchased automobile. One question asked for the owner's rating of the vehicle using categorical responses of average, outstanding, and exceptional. Another question asked for the owner's education level with the categorical responses some high school, high school graduate, some college, and college graduate. Assume the sample data below are for 500 owners who had recently purchased an automobile. Education Quality Rating Some HS HS Grad Some College College Grad Average 30 30 20 60 Outstanding 50 50 50 90 Exceptional 20 20 30 50 a. Use a 0.05 level of significance and a test of independence to determine if a new owner's vehicle quality rating is independent of the owner's education. Compute the value of the x test statistic (to 2 decimals). Use Table 3 of Appendix B to find the p-value. The p-value is - Select your answer - What is your conclusion? - Select your answer - v…

An industrial-organizational psychologist is interested in discovering the relationship between the tempo of preferred music that is played in a workplace and employee mood. Employees chose their favorite song on an MP3 player and then reported their moods when listening to that piece of music. A total of 10 participants were asked individually and brought in their own MP3 players; the least number of songs on an employee's MP3 player was 350. The sample data are presented as a scatterplot below. The psychologist wants to use a Pearson correlation coefficient to analyze the relationship. Considering the assumptions for this statistic, which of these statements is the correct course of action? A. The researcher has chosen the wrong statistic to represent this relationship. B. The researcher has violated a robust assumption and should be able to calculate r. C. The researcher has chosen the right statistic because all the assumptions are valid. D. The researcher has violated a…

An engineer wishes to compare the wearing qualities of two types of automobile tires, A and B. One tire of type A and one of type B are randomly assigned and mounted on the rear wheels of each of eight automobiles. The automobiles are then operated for a specified number of kilometers, and the amount of wear is recorded for each tire. The results are recorded in the following table. Automobile 1 2 SAWN 3 7 8 9 10 11 Amount of wear Tire A 10.5 9.7 12.4 9.7 8.7 11.5 10.8 9.9 9.0 10.3 12.0 Tire B 10.2 9.3 11.9 9.2 8.3 11.2 10.4 9.5 8.8 9.0 10.5 Assume that the distributions for both populations are normally distributed and a = 0.05. Answer the following questions using the data given in the above table. You may use any statistical output from any software to help you solve the following problems. a) Check the assumption of variances that is required to test the difference in the mean wear for the two types of tires. You may use either the confidence interval or hypothesis test to check on…
