Density function for a series of processes
The density function for a series of processes is fX (x) = 3/2x^2 for ?1 < x < 1. Choose 10 numbers independently from this distribution and find P(at least one is more than .5)

What is the probability that the fifth email received will be the second piece of spam? What is the mean number of emails until the second piece of spam arrives?
Find (or estimate) the P value. Sektch the sampling distribution and show the area corresponding to the P value. (alternate method: Find the critical value(s) and sketch the critical regions and sample test statistic on the normal curve).
Suppose the conditional distribution of Y given X = x is Gamma with ? = 4 and ? = 1/x and the marginal distribution of X is exponential with mean 2 a)Find the conditional mean and variance of Y given X = x.
From the following list, single out those measurements for which the square root of a typical measurement is a proper estimate of the standard deviation of the distribution from which the measurement is drawn:
The diameter of a certain buleet is known fo have a normal distribution with Standard deviation= 0.01cm. A random sample of size 10 yields an average diameter of 1.50cm. Find a 99% two sided confidence interval on the mean bullet diameter.
If z is a standard normal random variable, compute the following probabilities by standardizing.
A) What is the lottery's expected profit per ticket? B) What is the lottery's standard deviation of profit per ticket?
Usually statisticians use an alpha level of either 0.01 or 0.05 or 0.10. Describe what a statistician is trying to avoid by setting the alpha level to be a small number.
The Comfort Widget Company makes several different sized widgets. The smallest widget the company manufactures has a mean diameter of 2.35 inches with a standard deviation of .25 inches. The distribution of measurements for this widget's diamete
