Suppose thatX is a Poisson random variable with i = 6. Round your answers to 3 decimal places (e.g. 98.765). (a) Compute the exact probability that X is less than 4. (b) Use normal approximation to approximate the probability that X is less than 4. Without continuity correction: With continuity correction:i (c) Use normal approximation to approximate the probability that 8 < X < 12. Without continuity correction: i With continuity correction: i

The value, V, of a Tiffany lamp, in dollars, t years after 1975 is given by V(t) = 225(1.15)* . Which of the following expressions is the average value of the lamp between 1975 and 2020? 45 1 S 225(1.15)*dt 45 О 45 | 225(1.15)* dt V(0)+V(45) 2 O None of the others are correct. V(45)–V(0) 45 45 1 S 225(1.15)'dt

Unanswered a Save (%-D) #3 Insurance C An insurance company sold 8,000 policies ($100,000 payout value) this year. The probability of death for each person has been determined to be .002. The company charges $225 for each policy. Use the Poisson approximation to determine P(They lose $300,000 or more) Type your numeric answer and submit Unanswered HSave

When a man observed a sobriety checkpoint conducted by a police​ department, he saw 656 drivers were screened and 5 were arrested for driving while intoxicated. Based on those​ results, we can estimate that P(W)equals=0.00762​,where W denotes the event of screening a driver and getting someone who is intoxicated. What does P(W) ​denote, and what is its​ value? What does P(W) ​represent? P(W)=
