Question

Given a binomial experiment with p=0.8p=0.8 and 150150 trials, find the mean and standard deviation, rounded to three decimals, and then use the normal distribution with the continuity correction to find: (a) P(X≤119)=P(X≤119)= (b) P(X≥119)=P(X≥119)= (c) P(X=119)=P(X=119)= (You may find it helpful to use the Normal Distribution Tool.)

Step 1

8, q = 1 − p = 0.2 - Mean μ = np = 150 × 0.8 = 120 - Variance σ² = npq = 150 × 0.8 × 0.2 = 24 - Standard deviation σ = sqrt(24) ≈ 4.899 Show more…
