Question 3 (8 marks) Assuming that the average daily infections of COVID-19 is 600 with a standard deviation of 70 infections. The infections were recorded over a week as follows (500, 470, 590, 660, 720, 690, 510]. Do these data provide a significant level that the actual average for that week is worse than 600? Test at 94% significance level and determine the strength of evidence if exist. Show your steps
