Chapter 11, Section 11.3, Problem 021 Consider the following contingency table that is based on a sample survey. Column 1 Column 2 Column 3 Row 1 133 83 84 Row 2 90 52 | 91 | Row 3 1367996 a. Write the null and alternative hypotheses for a test of independence for this table. Ho: Rows and columns are H: Row and columns are b. Calculate the expected frequencies for all cells assuming that the null hypothesis is true. b....
For the two variables of interest: Create a scatter plot with Percent Time Asleep as the independent variable x and Longevity as the dependent variable y. The plot must include an informative title, along with correct labels for both axes. Include a plot of the least-squares equation (see #5 below). Calculate the correlation coefficient and the coefficient of determination. Identify any data points on the scatter diagram that appear to be influential. Use Cook's Distance > (4⁄√n) as the criterion...
U 4 5 The data table represents the measure of a variable before and after a treatment. Does the sample evidence suggest Individual that the treatment is effective in decreasing the value of the response variable? Use the c = 0.10 level of significance. Before, Xi Complete parts (a) through (d). 2 3 30 53 40 47 40 After, Yi 37 33 50 46 35 (a) What type of test should be used? Choose the correct answer below. O A....
For the following two datasets labeled y1 and y2 match one quantity in column A with one quantity in column B. The sample means and variances are labeled as y1, y2, S12 and S22. The population means and variances from which they were drawn are labeled μ1,μ2, σ12, and σ22. Assume that the two samples are independent random samples. H0: μ1=μ2 against the alternative Ha: μ1≠μ2 using significance level α=.01. Using the data from problem 1 provide the following information...
Select the BEST answer for each of the questions below (I true, F- false). Cirele the letter that corresponds with the answer you have selected. Each question is worth 2 points. [Total 40 points) Answer uestion E1. Power is the ability to reject the null hypothesis when it should be rejected 2. With curvilinear data, the Pearson r statistic is an appropriate, accurate statistical tool In a research report, the term statistically significant is used to indicate that the null...
The following ANOVA model is for a multiple regression model with two independent variables: Degrees of Sum of Mean Source Freedom Squares Squares F Regression 2 60 Error 18 120 Total 20 180 Determine the Regression Mean Square (MSR): Determine the Mean Square Error (MSE): Compute the overall Fstat test statistic. Is the Fstat significant at the 0.05 level? A linear regression was run on auto sales relative to consumer income. The Regression Sum of Squares (SSR) was 360 and...
