4. At this point in the semester, we have learned about 3different test statistics. These are z-scores, t-scores, and nowin this chapter we have x² We have previously used thecalculator to find p-values for tails cut by critical values for z-scores and for t-scores. Find the degrees of freedom (df) andthe p-value for a tail that has a critical value of x² = 6.92 and isfor a test for independence for a table with 3 rows and 4columns?O df = 12, p-value = 8.02.df = 6, p-value = 0.00022.df = 12, p-value = 0.00001.df = 6, p-value = 0.32831df = 12, p-value = 0.86285.

Assignment #6 For this assignment, you will be using the Tips Dataset file in Excel. The file contains both qualitative and quantitative variables. Choose two qualitative variables. You will be using a hypothesis test to determine if the two variables are associated. 1. Which two variables did you choose? Create a table to summarize the data from the data file. Example below: Example: Listed below are data from a survey conducted recently where Males and Females responded to their happiness with their supervisor (this is fictitious data). Response Male Female Total Not at all 23 25 48 Somewhat 13 22 35 Very Total 26 16 42 62 63 125 2. Which hypothesis test is appropriate for this type of data? Explain. What is your null hypothesis? What is your alternative hypothesis? 3. Conduct the hypothesis test. Include any output from Excel. What is your test statistic? Using alpha = 0.05 determine the results of your hypothesis test. Explain. 4. Interpret your results into a conclusion based on…

The final 2 parts of 5he question is (e) Find the value of the coefficient of determination r2. What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? What percentage is unexplained? (Round your answer for r2 to three decimal places. Round your answers for the percentages to one decimal place.) r2 = explained % unexplained % (f) For a neighborhood with x = 30 hundred jobs, how many are predicted to be entry level jobs? (Round your answer to two decimal places.) hundred jobs
Scenario: Is there a relationship between test scores (X) and presentation type (Y)? Test scores were quantified using the % correct. Students were able to choose the presentation type of their test — they could take the test online or in-person. Question: What is the scale of measurement for variable X in this scenario? Nominal Ordinal Scale

IQ tests supposedly measure our intelligence. They typically are ‘normed’ so that they have a mean of 100 and a standard deviation of 15. (Higher scores show higher intelligence.) Use the graph and use the z-score and percents from columns b and c in Table A, when relevant. If you scored 132, what is your z-score? (Interpret.) Use table A X, z(a), (b), and (c) X z (a) (b) (c) and use the graph! Write down or save your response to use in Part 2 of this quiz. Group of answer choices -2.53 z.
