3A Continuity Correction must be used with both Binomial and Poisson.
- ARichtig
- BFalsch
4When doing Continuity Corrections, standardising is not important.
- ARichtig
- BFalsch
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]
- A50
- B30
- C100
- D0.01 and 0.09
- E0.05 and 0.15
- 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])- A6.5<X>9.5
- B7.5<X>8.5
- C4.5<X>7.5
- D5.5<X>7.5
- E4.5<X>8.5
- F6.5≤X≥9.5
7What must both values equal for a Continuity Correction for the Normal Approx. to the Poisson?
- Aλ
- Bn
- Cμ
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)
P(X≥25) → P(X[blank_start]>24.5[blank_end])- A<33.5
- B<34.5
