WebApr 19, 2024 · The expected value of continuous random variable X with pdf f (x) and set of possible values S is the integral of x * f (x) over S. The variance of X is the expected value of X -squared minus the square of the expected value of X. Expected value: to approximate the integral of x * f (x) over S = [0, 1] (i.e. the expected value of X ), set g (x ... WebIn R, simulate a dataset with a continuous outcome variable and two continuous exposure/treatment variables, and an interactive effect of the two exposures/treatments. Then, make a figure that shows the relationship between the outcome and one of the exposures, holding the other exposure constant at its minimum observed value. Finally, …

WebA continuous random variable X has a normal distribution with mean 50.5. The probability that X takes a value less than 54 is 0.76. Use this information and the symmetry of the density function to find the probability that X takes a value greater than 47.
WebRandom variables are outcomes related to random processes. So for number of outcomes in a week to generate random variables, one has to assume that on any given day, one decides to exercise or not randomly. In reality, one decides based on his schedule that may vary systematically and hence difficult to be random. blackhead lancetWebThere can be 2 types of Random variable Discrete and Continuous.
