Independent Sample t tests. For each question, conduct every step of the Hypothesis testing process! 1. Ruwayda hypothesized that money would impact competitiveness. To test this, she randomly assigned people to either the control or experimental group. Everyone took a survey on competitiveness but those in the experimental group saw a poster with a picture of paper money on the wall while they took the survey. Based on her data, what should you conclude about money's impact on competitiveness scores? Use a .05 level of significance. What is the 95% confidence interval for this study? Control x = 5.79 SS = 26 n = 10 Experimental x = 6.13 S = 1.8 n = 10

Answers that need formulas must have them within the answer cell. A manager is trying to educate employees on the effects of personal health and workplace performance. The manager has gathered data from a group of employees to evaluate the effects of sleep and sickness.  The manager asked employees to record the total number of hours of sleep they had over 10 working days in two weeks and compared it to the number of sick days that each took over those 10 days. Sick Days Total hours of sleep 0 80 2 40 1 60 0 70 3 50 2 90 4 35 1 68 0 72 2 55   The manager wonders if a non-linear model is a better relationship between the variables. Develop the model and run a regression adding the non-linear variable for total hours of sleep.
