- Calculate the variance of a random variable X whose characteristic function is (1+ e3it)² f(t) = 4Let ZZ be a discrete random variable taking one of the four distributions covered in Chapter 10. Suppose you know that Var(Z)=(k+1)E(Z)Var(Z)=(k+1)E(Z) where kk is the last non-zero digit of your student ID number. Determine the distribution of ZZ and find its parameter(s), explaining your argument carefully.Find the variance of the random variable X with a PDF given by 3x2 S* if - 1< x< 1, f(x) = 2 otherwise. Submit your answer in fractional form.
- Let X be a random variable and a real number. Show that E(X - a)² = varX + (µ − a)² Hereμ = EX is the expected value of the random variable X and varX = E(X - μ)^2 is the variance of the random variable X. Guidance: start from the representation - (X-a)^2 = (X µ + μ- a)^2 and group the right side of the representation appropriately into the form (Z + b)^2, where Z is some random variable and b is a real number and open the square. The task should be solved with the help of the expected value calculation rules.Suppose that Y is a uniform continuous random variable on the interval (1,11). Calculate the expected value of the random variable (Y− 1)². Use one decimal place accuracy.Suppose X and Y are independent random variables with expected values E[X] = 0, E[Y] = 0, and Var(X) = 1, Var(Y) = 1. What is Var(X-Y)?

In each trial r¡ products are tested and Y;, the number of satisfactory items in the trial, is assumed to follow the binomial model Y; Bin(ri, p), where p is the proportion of satisfactory items in the production process. Using inspection data (rı, yı), (r2, Y2), …‚ (˜n, Yn) and assuming independent trials, the following log-likelihood for p was obtained ... l(p; data) = 25.8392 + 35 · log(p) + 17 · log(1 − p). A) Determine which of the following (r1, y₁), (r2, y2), …‚ (˜n, yn) is the correct data that yields the given log-likelihood 1(p; data). Note that you do not need to develop the likelihood from scratch, but to carefully look and use results shown in lectures, notes and exercises. B) Write the maximum likelihood estimate p.
