Moment generating function for a random variable
The moment generating function for a random variable X is given by Mx(t) = (1/4)+ (3/4)*(1/(1-t)), t>1. Determine formulas for the density function and distribution function. Sketch graphs for fx and Fx.

Data with 250 observations are drawn from a bell-shaped distribution with a mean of 50 and a standard deviation of 12. Approximately how many observations are more than 74?
A random variable X has a uniform distribution between 4 and 14. Find the probability that the random variable will take a value less than 7.8.
One of the issues facing organizations is increasing biodiversity throughout the organization. Once of the ways to evaluate an organization's success at increasing diversity id to compare the percentage of employees in the organization in a partic
Fit both logistic and probit models, modelling proportion killed as a function of nicotine concentration. Are there any obvious differences in the fit of these models?
In a recent survey, 72% of the community favored building a health center in their neighborhood. If 14 citizens are chosen, find the probability that (A) exactly 10, (B) between 8 and 12, (C) at least 8, (D) at most 7 of them favor the building of
Therefore it is an experiment of comparing three populations by selecting independent samples. Use a Kruskall- Wallis test to test the null hypothesis that the populations have the same median, with alpha=0.05.
A health care facility is interested in monitoring the primary C-section rate. Monthly data on the number of C sections collected over the two and half years is shown below.
The mean assembly time for a random sample of 36 carts, using the new method, was 40.6 minutes, and the standard deviation of the sample was 2.7 minutes. Using a 0.05 level of significance, can we conclude that the assembly time using the new meth
What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right tailed, or two tailed test? Identify the sampling distribution you will use: the standard normal or the Students t distribution. What is
