IYou have collected data about the amount of sleep that SJSU students get, guessing that the mean amount of hours of sleep per night across all SJ SU students (the population mean) is 8 Hours. We have a sample of students for whom their mean hours of sleep per night is 6.25 Hours. The standard error is 0.5 hours. Conduct a Z Test by following the steps below and completing the bold sections. 'Make a null hypothesis and a research hypothesis Null Hypothesis Ho: Nondirectional Research Hypothesis H1: 'Decide a-level (a = .05) and nature of test (two-tailed) 'Set critical z: (+/- 1.96) 'Calculate descriptive statistics 'Calculate Z : Z = (Sample Mean Population Mean) / SE Compare your 2 Test Statistic with the Critical Z Score (1.962 or -1.96z). 'Make a decision about the null hypothesis (reject or accept). Write a sentence describing what this means about your sample mean and estimated population mean
