Consider the following set of dependent and independent variables. Using technology, check for the presence of multicollinearity. If multicollinearity is present, take the necessary steps to eliminate it. Select the correct choice and, if necessary, fill in the answer boxes to complete your choice. A) Eliminate the variable x(__), which has a VIF of (__). No more variables need to be eliminated. B) Eliminate the variable x(__), which has a VIF of (__). Then eliminate the variable x(__), which has a VIF of (__). C) No variables need to be eliminated. y 33 31 38 37 40 46 48 54 47 58 x1 53 55 55 58 57 61 66 70 89 71 x2 24 17 20 17 9 15 14 11 15 12 x3 7 16 10 13 19 18 24 21 28 30

For this exercise, you must input thew following data: Variable name: Low-sugar diet; label: low_feed_consumed: 8.5, 8.0, 13.2, 6.8, 6.45, 6.0, 9.12, 9.75. Medium-sugar diet; medium_feed_consumed: 10.99, 10.5, 9.67, 8.61, 10.92, 12.8, 9.03, 9.45. High-sugar diet; high_feed_consumed: 10.39, 9.97, 13.78, 12.69, 12.8, 9.67, 9.98, 10.67. 2.a) Complete a one-sample t-test. You are testing the low sugar diet mean against the medium sugar diet mean 10 (rounded to a whole number). Also provide the obtained t-value, level of significance and state whether you accept or reject the null hypothesis.
In a test of the hypothesis that females smile at others more than males do, females and males were videotaped while interacting and the number of smiles emitted by each sex was noted. Using the following information regarding number of smiles in the five-minute interaction, examine whether there are sex differences in the number of smiles. Males Females N1 = 5 N2 = 5 X1 = 7.6 X2 = 15.2 S12 = 17.04 S22 = 8.96 Which is the independent variable and which is the dependent variable? What is your research hypothesis? What is your null hypothesis? Which test should you use (Two Sample Independent t, ANOVA, Chi-square, or correlation )? Calculate the test statistic. interpret whether you have statistically significant results when α = .05. State whether the null hypothesis is rejected. Include critical region.

MR In Dave Eggers’ novel The Circle, a mysteri-ous technology company has developed a strangely data-driven work environment in which employees are assigned a performance score that seems to be the product of factors in their social activities and environment, such as the extent of their engagement in work community and the number of times they post on the company’s social media site. Using the fictional data below, compute r and r2 for each com-bination of two variables from this novel and test the correlations for their significance. Write a paragraph interpreting the relationships between these vari-ables, and what they might mean for the company
