Test the significance of each independent variable using α = 0.05. Test the significance of x₁. Identify the null and alternative hypotheses. Ho B₁ = H₁ B₁ 0 0 (Type integers or decimals.) Calculate the appropriate test statistic. The test statistic is 4.20 (Round to two decimal places as needed.) Determine the appropriate critical value(s) for α = 0.05. The critical value(s) is (are) ☐ (Round to two decimal places as needed. Use a comma to separate answers as needed.)

Sample 1 Sample 2 n1 = 10 n2 = 30 71 = 22.6 E2 = 20.7 81 = 2.5 82 = 4.4 a. What is the point estimate of the difference between the two population means (to 1 decimal)? b. What is the degrees of freedom for the t distribution (round the answer to the previous whole number)? c. At 95% confidence, what is the margin of error (to 1 decimal)? d. What is the 95% confidence interval for the difference between the two population means (to 1 decimal and enter negative value as negative number)? 0= Icon Key

Page 2 of 2 Assignment 2: (CLO 5): MS Excel application: Determine any four related variables, two of them are qualitative (Categorical) and two are quantitative (Numerical). a. Input sufficient data about the four variables (a random sample of 50 or more) in MS-Excel sheet. b. Prepare frequency distribution tables for one qualitative and one quantitative variable. c. Prepare appropriate graphs for each of the two tables. d. Prepare a pivot table (cross tabulation) consists of two qualitative variables (in rows and columns) and one quantitative variable as values. e. Conduct descriptive analysis for the two quantitative variables (summary measures). f. Find the coefficient of variation (CV) and compare the dispersion of the two variables.

Assume that the sample is a simple random sample obtained from a population with a normal distribution. Construct separate 90% confidence interval estimates of a using the two-line wait times and the single-line wait times. Do the results support the expectation that the single line has less variation? Do the wait times from both line configurations satisfy the requirements for confidence interval estimates of a? Click the icon to view the data on wait times. Construct a 90% confidence interval estimate of σ using the two-line wait times ☐ second(s) << second(s) (Round to the nearest whole number as needed.) Question Viewer
