Question 6 Part 1 of 5 A study assessed fatigue in Chicago public school teachers due to stress. A random sample of 14 teachers had the following post-work heart rates: 63.2 67.6 71.1 72.6 62 68.3 68.5 61.8 65.8 72.1 60.7 69.1 67.9 66.5 Assume that the population standard deviation of post-work heart rates for Chicago public school teachers is 4 bpm, also assume that the sample is from a normal population. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean post-work heart rate for Chicago public school teachers is different from the normal resting heart rate of 72 bpm? (Note: The average and the standard deviation of the data are respectively 66.94 bpm and 3.84 bpm.) Procedure: Select an answer Assumptions: (select everything that applies) Population standard deviation is known Simple random sample Normal population Sample size is greater than 30 The number of positive and negative responses are both greater than 10 Population standard deviation is unknown Question Help: Video Written Example Submit Part
