1) Collect data from n = 10 individuals you know about the number of hours they slept last night. Show your data. A: 4,5,5,6,7,7,7,8,8,9 2) State your null and alternative hypotheses. Is this a one-tailed or a two-tailed hypothesis? Why? A:One tail hypothesis 3) Calculate the sample mean (M) for the data you collected. Select the alpha (.05, .01). What is your resulting critical value(s)? 4)Calculate the test-statistic (obtained Z)! You can use a population mean = 8 (hours), a population standard deviation = 1 (hour), your sample mean, and your sample size of 10. make sure to show your steps so that others can check your calculations!!! 5) Now it's time to compare your test statistic (obtained Z) to the critical value and decide about rejecting, or failing to reject, the null hypothesis. 6) What does this mean about how your sample compares to the population? Is there a significant difference between the sample mean and the population mean? Based on the characteristics of your sample, why might this be? 7) Why is it important to form your hypotheses before collecting your data
