b) In a study of all residents from City A, sixty Covid-19 cases have been detected. Among these confirmed cases, most of them have the symptoms of fever. The following temperatures (°C) of a resident were collected within fourteen days of self-quarantine. 36.7 37.5 36.8 38.1 36.8 38.6 38.4 37.9 35.8 36.6 38.3 37.1 37.2 36.5 With the use of t-test to perform the hypothesis testing when variance of population is unknown at the 99% significance level, do the data provide sufficient evidence to conclude that the average temperature of all residents from City A is more than 37.1 °C? Step 1: Hypothesis Statement Null Hypothesis Ho : u Alternative Hypothesis H1 : µ °C Step 2: Test Statistic n = 14 x = 37.0°C S = [3 d.p.] t-test = [3 d.p.] Step 3: Significance Level @ Level of Confidence critical value of t = [3 d.p.] Step 4: Conclusion / Decision Rule Reject or fail to recject HO
