- The relationship between probability distribution function F(x) and the probability density function d f(x) is f(x) = -F(x) dx Select one: True False10) Let f(x) by the probability density function of some continuous random variable. Explain why it must be true that f(x) dx =1.Show that the standard normal probability density function f(x) has points of inflection when x = ±1.
- The probability density of the random variable Z isgiven by f(z) = kze−z2for z > 00 for z F 0Find k and draw the graph of this probability density.The probability density function of the continuous random variable X defined in the set of non-negative real numbers is given as f(x) = 2.exp(-2x). What is the expected value of X?Let X₁, X2, X3, X30 be a random sample of size 30 from a population distributed with the following probability density function: f(x) = (0, -, if 0Let X be a positive random variable having the probability density function fx(x) and 1 Y = be a decreasing function for 0The random variable X has probability density function 3, 1< a < 2 f(x) = otherwise. Calculate Var(4X +7).Suppose a college professor never finishes her lecture before the end of the class period, and always finishes within five minutes after the class period is supposed to end. Let X = time that elapses between the end of the class period and the actual end of the lecture. Suppose the pdf of X is: (image) Find the value of k that makes f(x) a legitimate probability density function, and use that value of k to find the probability that the lecture ends less than 3 minutes after the class period is supposed to end.Suppose that X and Y have a joint probability density function given byThe probability density function of a continuous random variable is given by 1 1 4 f (x) = - 4 for x > 0. a) Find P(X> 5). b) Find the mean of X. c) Find the CDF (cumulative distribution function). d) Use the CDF to find the median of X.A random variable X has probability density function (x² + 2x + 4) for 0 < x < 3 f(x) = otherwise. Which of the following gives the cumulative distribution function F(x)?SEE MORE QUESTIONSRecommended textbooks for youMATLAB: An Introduction with ApplicationsStatisticsISBN:9781119256830Author:Amos GilatPublisher:John Wiley & Sons IncProbability and Statistics for Engineering and th…StatisticsISBN:9781305251809Author:Jay L.
