With 10 organisms expected in one cubic meter of discharge, there are H = 0.8(10) = 8 organisms expected in 0.8 cubic meters of discharge. Therefore, the standard deviation rounded to three decimal places is a = VA = 2.828 2.828 . Substitute the values ( = 8 and o into the inequality determined in the previous step, X / + 20, rounding to three decimals. X H + 20 X 8 + 5.656 5.657 X 13.656 13.657 Step 5 Recall that the table of cumulative Poisson probabilities is in terms of P(X s x). We can reframe the probability to fit the P(X s x) format using P(X 13.657) = 1 - P(X $ 13.657). Because the Poisson distribution is a discrete probability distribution, the table of cumulative Poisson probabilities provides values for integer x-values. Therefore, for a conservative probability calculation, round the value of x down to the nearest whole number, 13. Use the cumulative Poisson probability table and the previously calculated value u = 8 to calculate P(X $ 13), rounding the result to three decimal places. P(X $ 13) = X Substitute the value of P(X $ 13) into the equation below to calculate P(X 13.657), rounded to three decimal places. P(X 13.657) = 1 - P(X $ 13) SUBMIT SKIP (YOU CANNOT COME BACK) Need Help? Read It Watch It Attac SUBMIT ANSWER 6 SP 500 Inam -0.33% Search 2NVIDIA G-SYNC LG F2 ON # W DP UT tab m
