[size=150]True or False. If the distribution is a probability distribution, then each probability is between 0 and 1?[/size][br]
[size=150]4) Determine whether the distribution is a probability distribution: (in table form)[br] x: 1 2 3 4 [br] P(x): 0.25 0.48 0.23 0.11 [/size]
[size=150]Part A) Determine Yes or No: ______[/size][br][br][br][size=150]Part B) Find the ∑ P(x) = ? _______[/size]
[size=150]Construct population parameters of a Binomial Distribution given n= 5 and p = 0.6. Determine q, mean (μ), variance(σ^2), and standard deviation (σ).[/size][br]
[size=150]q = 1 - p = 0.4[br]mean (μ) = n*p = (5*0.6) = 3[br]variance(σ^2) = npq = (5*0.6*0.4) = 1.2[br]standard deviation (σ) = (npq)^0.5 = 1.0954[/size][br]
