Obstacle Course Times An obstacle course was set up on a campus, and 12 volunteers were given a chance to complete it while they were being timed. They then sampled a new energy drink and were given the opportunity to run the course again. The "before" and "after" times in seconds are shown below. Is there sufficient evidence at a=0.10 to conclude that the students did better the second time? Assume the variables are normally distributed.

Using the x²-test check which distribution better fits the data (e.g., results in smaller chi-square statistic). For the negative binomial use r=4 and p = 0.44, and for the Poisson use λ = 4.6.
Micah is interested in testing whether college students' levels of gratitude change over the course of the semester.

Dataset: NES. Variables: spend8, nesw.) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the Analyze ▶ Compare Means ▶ One-Sample T Test procedure. You then will draw inferences about the population mean. Make sure you weight observations using the nesw variable so your results are nationally representative. A. The spend8 variable has a sample mean of ______.
