2-10pts For the data listed above calculate the mean and the variance (you can use excel calculator and just put results)? Mean (H) - M - XX 9 019 194990 89993.02 Variance (0) - Z Y-M) = 3910332583 3-15pts Pick a random sample, X, of 10 days from the data and list it below (dates and values)? Selected Date Number of new cases 2020-4- 29865 2020-4- 2 34173 2020-4-3 38689 2010-4- 4 4249 2020-4-5 48736 2010 -652279 2010 -4. 55949 2090-- 8 61474 2070-4- 65892 2020-4-10 74605 4-10pts. Assume that the population (number of new cases in your assigned country) follows a Normal Distribution with unknown mean, u and has the known variance. eyou calculated in part 2 Design a moment based estimator to be used to estimate the mean of the distribution? Using your estimator, find an estimate for M = ?? 3910332583 Estimator A = Estimate = 5-10pts. Show whether your moment based estimator is biased or not and calculate its variance

Answer 1

t e be a random variable that donato number of new cases. xon Nreg 8²) unknown To known. fon harmal distribution - EL-д → Estimaton of l is w sx = 277 23.02 Now =t, 6(x) - nusu Hence it is unbaised. - Ivan (xi) - none = 0;? 02: can be calculated from the data beg using § (xi-Q)? he formula Using male.
