Question 15 We have sampled a number of values X1 = -1, X2 = -2, X3 = 0, X4 = 1, X5 = 2). Suppose X1, X2, X3,-, X5 are i.i.d. random variables that follows the probability density function Not yet answered f(x;o) = 1 V2 o e-2/ Marked out of 4.00 Please find the maximum likelihood estimator of o Flag question Round your answer to three decimal places. Answer:
Question 16 Not yet Suppose that 70% of people prefer beef over lamb. We randomly sampled 1000 people. What is the probability that the sample will have no more than 710 people who prefer beef over lamb? Please use the normal approximation to the probability distribution, and you don't need to use continuity correction here. answered O 0,60 Marked out of 3.00 O 0.7549 Flag question O 0.2451 O 0.40 O None of the other answers
