Problem 5. The number of orders per week, X, for radios can be assumed to have a Poisson distribution with parameter 35. (a) Find P(X 2 35 and P(X 25). (b) If the number of radios in the inventory is 38, what is the probability of a shortage occurring in a week?

Suppose the number of patients per week that visit a health center follows a Poisson distribution with a rate of 300 patients per week. Let the random variable X count the number of patients per week that visit the health center. A) State the distribution of the random variable defined above B) Compute the probability that during a randomly selected week exactly 280 patients visit the health care center C) Compute the probability that during a randomly selected week at...

For each problem below, state the distribution, list the parameter values and then solve the problem. You may use Excel to solve but you still need to list the distribution name and parameter value(s). For example: Poisson distribution, x=5, p=0.24, P(5; 0.24) = 0.78 a) A skeet shooter hits a target with probability 0.6. What is the probability that they will hit at least four of the next five targets? b) You draw a random sample of 12 first graders...

each trial, the mean of the distribution is assumed to be mp, where n is the number of independent trials. 4 Point Extra Credit: Derive the Expected Value of X by constructing a TABLE to describe the probability density funetion b and the cumulative distribution function for the binomial distribution with n-13 and p37 (forx-0,1,2, ...n). Solve using the binomial formula to 8 decimal places. Additional Point Extra Credit: Using the TABLE you constructed, also find the Varianee. Compare the...

Answer 5 and 6, using R programming code: 5. We have seen the following functions dnorm pnorm qnorm normal probability density function normal cumulative distribution function normal quantile function a. Let X have a normal distribution with mean 100 and variance 100. Find the 90th percentile of X by calling the function qnorm in two ways: (i) specify the arguments by position, and (ii) specify the arguments by complete names. b. Find P(X > 90) using the function pnorm in...
