1. Explain how the exponential distribution differs for the normal distribution? 2. Explain the significance of the exponential distribution to one's decision-making? Explain how to get CDF from PMF. Provide an example of a Poisson distribution and explain why that example follows a Poisson distri...
Explain how to get CDF from PMF. For the probability density function shown below, what is the probability of the random variable X being less than 1/3? a) 0.11 b) 0.22 c) 0.25 d) 0.33 Explain how to find the mean value of the probability function. ...
Not a function: “one to many“. In other words, let’s say you had one x-value that maps to many y-values. For example, — in coordinate notation — (2,1) and (2,10). If the first number (the x-value) repeats, then you do not have a function. To put that another way, ...
Let’s say that a sequence of random variables Xnhasprobability mass function (PMF)fnand each random variableXhas a PMFf. If it’s true thatfn(x) →f(x) (for all x), then this implies convergence in distribution. Similarly, suppose that Xnhascumulative distribution function (CDF)fn(n ...
