2What is the formula for the Normal Approximation to the Poisson?
1. AX~N(λ,λ)
2. BX~Po(λ)
3. CX~N(μ,σ^2)
3A Continuity Correction must be used with both Binomial and Poisson.
1. AVerdadeiro
2. BFalso
4When doing Continuity Corrections, standardising is not important.
1. AVerdadeiro
2. BFalso
5For a Continuity Correction for a Normal Approx. to the Binomial, n must be greater than [blank_start]50[blank_end] and p must be between [blank_start]0.1 and 0.9[blank_end]
1. A50
2. B30
3. C100
4. D0.01 and 0.09
5. E0.05 and 0.15
6. F0.1 and 0.9
6Examples of standardising for Binomial:
P(7≤X≥9) → P([blank_start]6.5<X>9.5[blank_end])
P(5<X>8) → P([blank_start]5.5<X>7.5[blank_end])
1. A6.5<X>9.5
2. B7.5<X>8.5
3. C4.5<X>7.5
4. D5.5<X>7.5

8Examples of standardising for the Poisson:
P(X<34) → P(X[blank_start]<33.5[blank_end])
P(X[blank_start]>40[blank_end]) → P(X>40.5)
P(X=38) → P([blank_start]37.5<X>38.5[blank_end])
P(X[blank_start]≤64[blank_end]) → P(X<64.5)
