The output of a chemical process is continually monitored to ensure that the concentration remains withinacceptable limits. Let X be the number of timeseach week that the process is calibrated. The probabilityfunction, c(x) is given as:c(a) = ,x = 1, 2, 3%3DA random sample of 34 cases is selected from this population.i.Determine the expected value and variance of sample mean of X.ii.Find the probability that the sample mean is less than 2.4but is greater than 2.1?

(i). Mean = Σx*C(x) = (1/3+2/3+3/3) = 6/3 = 2 mean, u= 2 Variance= E(X2)-u2 E(X2)= Σx2*C(x) =…

Answered: The output of a chemical process is…

Trying to find variance. his equation is Prob(x)*[x-e(x)]^2. Just need an example to get me started.Original question is: A call center recieves an average of 10 calls per hour. Assuming the number of calls received follows the poisson distribution, determine the probability of each of the discrete outcomes below. Then calculate the variance component for each one using the standard formula for the variance of a discrete random variable. At the end, take the sum of both columns. Table: Poisson Distribution Table Calls Density Variance 0 0.00% 1 0.05% 2 0.23% 3 0.76% 4 1.89% 5 3.78% 6 6.31% 7 9.01% 8 11.26% 9 12.51% 10 12.51% 11 11.37% 12 9.48% 13 7.29% 14 5.21% 15 3.47% 16 2.17% 17 1.28% 18 0.71% 19 0.37% 20 0.19% 21 0.09% 22 0.04% 23 0.02% 24 0.01% 25 0.00% 26 0.00% 27 0.00% 28 0.00% 29 0.00% 30 0.00% Sum 100.00%

Let the random variable T follow a Student's t distribution with 9 degrees of freedom. State the distribution of the random variable T. Group of answer choices T∼Student′st(9) T∼Student′st(8) T∼Normal(0,1) T∼Student′st(0,1) Compute the probability that T is between −0.1 and 0.6. True or False: The larger the degrees of freedom in a Student's t distribution, the closer to a standard normal distribution the Student's t distribution becomes.
