\f1. (1 mark) What is the sample mean? million (3dp) 2. (1 mark) What is the sample standard deviation? million (3dp) 3. (1 mark) The most appropriate hypothesis test for these data is 4. (1 mark) The null hypothesis is that the mean estimated excess deaths from COVID-19 equal (Hint: this is the value of #o in the Ho: # = Mo) 5. (2 mark) What is the absolute value of the test statistic ? (3dp) 6. (2 mark) Is the p-value for this test statistic greater or less than 0.05? 7. (3 mark) Calculate a 95%% confidence interval to estimate the mean excess deaths due to the COVID-19 between 1 January 2020 and 31 December 2021. The Absolute Value of the Critical Value for a 95% confidence interval is (3dp) Lower Bound = million (3dp) Upper Bound = million (3dp) 8. (1 mark) What is the most appropriate conclusion for this test? A. The excess deaths are significantly different than the hypothesised value, possibly greater. B. The excess deaths are significantly different than the hypothesised value, possibly lower. C. The excess deaths could be the same as the hypothesised value
