26-30. What is the mean of the probability distribution? (include solution and box your final answer) 31-35. What is the standard deviation of the probability distribution? (include solution and box your final answer)
36-40. What is the variance of the probability distribution? (include solution and box your final answer)



Sagot :

Answer:

26-30 μ = 0(0.41) + 1(0.22) + 2(0.17) + 3(0.13) + 4(0.05) + 5(0.02) = 1.25

31-35 σ = 1.34

36-40 var = 1.81

See attached file for the solution.
