Closed form for the moment generating function
Find a closed form for the moment generating function of a discrete uniform random variable, that is, for the random variable X with pmf p(x) = 1/n for x = 1,2,3,....,n.(hint: use lemma 2.6.1.)

The scores of a random sample of 8 students on a physics test are as follows: 60, 62, 67, 69,70, 72, 75, and 78. Test to see if the sample mean is significantly different from 65 at .05 level. Report the t and p values.
One prominent physician claims that 70% of those with lung cancer are chain smokers. If his assertion is correct, the probability that 3 out 5 of such patients are chain smokers is?
The mean number of cigarettes smoked per day for the 298 people who did not complete the program was 13 with a standard deviation of 8.97. Construct a two-sided 95% confidence interval for the difference between means.
Generate two random numbers between 0 and 1 and take X to be their sum. The sum X can take any value between 0 and 2. The density curve of X is a curve that forms an isosceles triangle with the horizontal axis. It has height 1 and the base goes fr
Which of the following is the hypothesis test to be conducted? What is the test statistic? What is the P-value? What is the conclusion about the null hypothesis?
If viscous effects are negligible, what is the pressure in the suction pipe (the pipe between the lake and the pump) at an elevation 6ft above the lake?
Suppose you want to estimate the population proportion of statistics nerds at college. To do so, you take a sample of 100 students and find that 20 of those students were bona-fide, genuine statistics nerds. What is the lower limit of the 90% conf
Use graphical sensitivity analysis to determine the range of values of the probability of state of nature s1 over which each of the decision alternatives has its largest expected value.
A plastic casing for a magnetic disk is composed of two halves. The thickness of each half is normally distributed with a mean of 1.5millimeters and a stantard deviation of 0.1 millimeter, and the halves are independent. Determine the mean and sta
