A businesswoman is considering whether to open a coffee shop in a local shopping center. Before making this decision, she wants to know how much money people spend per week at coffee shops in that area. She took a random sample of 26 customers from the area who visit coffee shops and asked them to record the amount of money (in dollars) they would spend during the next week at coffee shops. At the end of the week, she obtained the following data (in dollars) from these 26 customers: 16.63 38.63 15.14 14.47 5.01 63.64 10.19 13.28 32.25 36.00 16.19 65.91 10.28 37.14 3.22 6.92 34.65 6.40 36.35 27.59 38.67 13.18 9.80 9.48 1.21 5.19   Assume that the distribution of weekly expenditures at coffee shops by all customers who visit coffee shops in this area is approximately normal. Round your answers to cents.a. What is the point estimate of the corresponding population mean?x¯=$b. Make a 99% confidence interval for the average amount of money spent per week at coffee shops by all…

A professor wants to know which type of instructional mode students had more satisfaction.  The professor randomly selected n = 5 students from each of the following types of classes: online only, hybrid, and face-to face only.  Student were given a satisfaction survey.  Are their differences in student satisfaction among the different instructional modes.  The data are below: Online Hybrid Face-to-Face 3 3 4 3 3 1 3 1 3 2 2 2 2 1 3 Using the table in the back of the book, find the critical value for F (Fcrit) with α = .05.

Dataset: NES. Variables: spend8, nesw.) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the Analyze ▶ Compare Means ▶ One-Sample T Test procedure. You then will draw inferences about the population mean. Make sure you weight observations using the nesw variable so your results are nationally representative.   A. The spend8 variable has a sample mean of ______.

A researcher is interested in determining if there is a relationship between handedness and penmanship.  To study this question, the researcher submitted samples from 100 students to penmanship experts.  The samples were rated to be of low, medium or high penmanship quality.  The observed frequencies were totaled according to left verses right handedness.     Penmanship Handedness low medium high Left 8 29 6 right 9 37 11   Which test is appropriate for this data? Why? Calculate row, column and table totals. State the null and alternative hypothesis. What is the degree of freedom? What is the value of the test statistic? What is the p-value? Are the data statistically significant at the 5% significance level? Do you recognize any flaws in this study
