Can you help me answer these problems?

13 If you doubled each number of days to completion in the Days (x) column, the variance of days to completion will be 4.7152 8.5773 9.4304 10.3683 Next THREE questions are related to the following: The expected number of days to completion for a different project is 3.55 days--E(x) = 3.55. The variance is 1.25--var(x) = 1.25. The project cost is made up of a fixed cost of $45 (thousand), plus variable cost of $11 (thousand) for each day taken to complete the project. 14 The expected value of the project cost is $_ thousand. a 84.05 b 79.55 76.45 39.05 15 The variance of project cost is a 161.85 151.25 58.75 13.75 16 The standard deviation of the project cost is $ 14.648 13.819 13.036 12.298 17 If you toss a balanced coin 60 times, the probability that you will get 30 tails is a 0.0733 0.1026 0.2872 0.50 18 If you toss a balanced coin 10 times, and receive $5 each time you get tails, the probability that you will earn $40 in this experiment is a 0.2136 0.1424 0.0791 0.0439The proportion ofvehicles which drive above the speed limit on a freeway is 76%. Suppose 10 i vehicles are randomly clocked. The following is the probability distribution of the number of 0 0.000001 vehicles which drive above the speed limit. [The blank cells are intentional!) -> 1 0.000020 19 The probability that at most 8 vehicles drive above the speed limit is 2 a 0.7327 3 b 0.7045 4- c 0.6774- 5 d 0.6514- 6 7 20 Ifeach speeding vehicle is issued a $200 speeding ticket, the expected value of the ticket 8 amount is $ 9 0.2030 1430 10 0.0643 14-90 a b 14-60 c d 1520
