- A cell phone company offers 6 different voice packages and 8 different data packages. Of those, 3 packages include both voice and data. How many ways are there to choose either voice or data, but not both?Imagine a database from the Gallogly College of Engineering that contained the starting salariesfor a sample of Spring 2021 graduating engineers. Recreate the following table. At theintersections of the table, fill out what happens to the sample statistic (in the row) when everysalary is altered by the specified amount (in the column). You’re welcome to use actual data totest your intuition, but data aren’t necessary – the answers in the intersections should begeneric.The manufacturer of an MP3 player wanted to know whether a 10% reduction in price is enough to increase the sales of its product. To investigate, the owner randomly selected 8 outlets and sold the MP3 player at the reduced price. At 7 randomly selected outlets, the MP3 player was sold at the regular price. Reported below is the number of units sold last month at the regular and reduced prices at the randomly selected outlets. Regular (7 outlets) - 138, 127, 129, 114, 114, 126, 98 Reduced (8 outlets) - 122, 135, 151, 133, 113, 129, 134, 133 At the 0.050 significance level, can the manufacturer conclude that the price reduction resulted in an increase in sales? Hint: for the calculations, assume the reduced price as the first sample. Compute the pooled estimate of the variance (round to 3 decimal places) Compute the test statistic (round to 2 decimal places)
- A 7th grade science teacher would like to know if spending more time doing class experiments will help his students perform better on tests. In a day, he teaches 4 periods of science, so for his 1st and 3th period classes, he taught as he normally does with mostly lectures and occasional class experiments. For his 2nd and 4th period classes, he did a class experiment every day with minimal lectures. There were n = 25 different students in each of his classes. He then wanted to compare the exam averages between his classes to see if student performance was significantly different. Which of the following statistical tests should he use? z-Test one-sample t-Test independent sample t-test dependent sample t-testA 7th grade science teacher would like to know if spending more time doing class experiments will help his students perform better on tests.

- A personnel office is gathering data regarding working conditions. Employees are given a list of five conditions that they might want to see improved. They are asked to select the one item that is most critical to them. Which type of graph, circle graph or Pareto chart, would be the most useful for displaying the results of the survey? Why? Pareto chart, because it shows the items in order of importance to employees. Circle chart, because it shows the items in order of importance to employees. Circle chart, because it shows the total number of important issues to employees. Pareto chart, because it shows the total number of important issues to employees.A 7th grade science teacher would like to know if spending more time doing class experiments will help his students preform better on tests. In a day, he teaches 4 periods of science, so for his 1st and 3rd period classes, he taught as he normally does with mostly lectures and occassional class experiments. For his 2nd and 4th period classes, he did a class experiment everyday with minimal lectures. There were n=25 different students in each of his classes. He then wanted to compare the exam averages between his classes to see if student preformance was significantly different. Which statistical tests should he use?A psychology instructor at a large university teaches statistics. There are 22 students in the class, and he has broken them into two groups. Each group has a different graduate assistant who is responsible for running separate breakout lecture and lab sections of the course. One graduate assistant (GA) has lots of experience teaching, while the other has more limited experience. The instructor wants to check for comparable learning across the two GAs, hoping students receive similar experiences (i.e., to find no difference). The data below are the scores (out of 100) of the students on the first midterm. Use it to test whether there is a difference between the groups. Group 1 (less experienced GA) Group 2 (more experienced GA) 60 70 65 85 69 72 58 83 57 81 59 69 52 65 72 75 70 79 65 71 75 80 Q: List the steps to obtaining all relevant statistical output in SPSS.

- A psychologist at the Hospital was asked to determine whether there was any clear difference in the length of stay (in days) of patients with different categories of diagnosis. The hospital was looking for ways to reduce costs and free up some more beds so that they could treat more patients from the community. They chose three diagnostic categories that they thought were possibly staying the longest and selected the 4 more recent admissions from each of these diagnostic categories: affective disorders, cognitive disorders, and drug-related disorders. The results are presented in Table 3 below. Using an alpha = .05 and showing all the steps of hypothesis testing, is there a significant difference in length of stay among diagnosistic categories?The file MidCity Download MidCitycontains data on 128 recent sales in Mid City. For each sale, the file shows the neighborhood (1, 2, or 3) in which the house is located, the number of offers made on the house, the square footage, whether the house is made primarily of brick, the number of bathrooms, the number of bedrooms, and the selling price. Neighborhoods 1 and 2 are more traditional neighborhoods, whereas neighborhood 3 is a newer, more prestigious neighborhood.

After using the shampoo, each consumer used an interval-level scale to rate his or her satisfaction with it. Scores could range from 0 to 100, with higher scores indicating greater satisfaction. Consumers didn’t know each other and were randomly assigned to three groups: (1) receive a store brand of shampoo in a bottle clearly labeled as such, (2) receive a premium brand of shampoo in the premium brand’s bottle, or (3) receive a store brand of shampoo in the premium brand’s bottle. Here are the collected data: Store brand, store bottle Premium brand, premium bottle Store brand, premium bottle 70 85 85 65 90 80 65 95 90 60 90 85 M = 65s = 4.08 M = 90s = 4.08 M = 85s = 4.08 SSbetween = 1400 c.
