k) Write a concluding statement which answers the question stated in the 1st paragraph of this question, i.e., near the top of p. 8. This statement should include the following information: - your decision (rejecting or failing to reject the null hypothesis); - state the specific groups being compared (What is the sample? What is the population?); - what is the dependent variable (the variable on which the groups are being compared); - a statement of whether or not the difference is significant; -If the difference is significant, report the means and standard deviations of the sample and population. (5 pts) An example would be: "We reject the null hypothesis, and conclude that the sample of 40 students from the Science Building courtyard had a significantly lower mean level of reported stress (M = 18.42, SD = 1.44) than the population of all WLU students (M = 16.00, SD = 1.55)." 1) Note that one of the values in our dataset for SleepTime_Num is 24. This must be an error. I re-ran the Descriptives command after this value was removed from the data set, and found that the sample mean was now 7.53 and the calculated Z value was now 1.67. In this case, would your decision be to reject the null hypothesis or fail to reject the null hypothesis? (1 pt) m) Does this decision mean that you believe that the difference in average hours of sleep between our sample and the population is more likely attributable to random variability or systematic variability (as discussed in class)?.
