I Given the following stem & leaves Table: Stem: 2 7 Leaves: 23 255 11 Find the following: The Mean, the Median, the Midrange, is it a single mode? (prove your answer)! And then find the Estimate of the Standard Deviation and Is x = 10 Unusual or Not? II Given the following Data: X = 2 3 P(x) = 0.413 0.182 0.095 0.114 0.04 Is this a Probability Distribution? If so, find the Mean (u) and the Standard deviation (6). If this is not a Probability Distribution, let the summation of P(x): (EP(x)) =P(A) Then find : 1) P(A)="Missing Row", to fill in the chart 2) the Minimum Usual Value. 3) is (i) 1.2 a Usual-Value? (ii) is 2.5 a Usual-Value? (Give your Reasons for each)! Choose One between the next two(2) Problems (1) & (2): III 1) Which one of the following bet is better: Going to a Casino and betting $8 on a game with P(winning) =1/38 and a Prize of $296 or betting on a small town Lotto with Expected-value of -0.25? Find the Odd-in Favor of that bet & the Payoff-Odd for Every $2 bet ! 2) Cathy went to the casino and bet on # 11 of a game which P(Losing) = 45/46 which Payoff-odd is 129:3, Given that the Net Profit is $301 , Find: a) the Prize ; b) the odd-against that bet; Is she better off with that bet or a bet on a small town Lotto which Expected -Value is -0.3
