State the Null and Alternative Hypotheses. Determine the test statistic. Determine and interpret the p-value
Let X be a random variable of the continuous type that has pdf f(x). If m is the unique median of the distribution of X and b is a real constant, show that E(X - bl) = E(X - ml) + 2 [(b - x)f(x) £lx, provided that the expectations exist.
given a standardized normal distribution with a mean of 0 and a standard devication of 1 determine the following
Nationwide, the average time until a electric utility customer service representative answers a call is 260 second. The Gigantic Kilowatt Energy Company randomly sampled 30 calls and found that, on average, they were answered in 227 second with a ..

the probability density function for the diameter of a drilled hole in a metal shop plant is 10e-10x-5 for x gt 5mm.
Show that if a 2D Gaussian random vector Y- = (Y1, Y2) has un- correlated components Y1, Y2, then those components are statistically independent random quantities.
Medical studies have shown that 10 out of 100 adults have heart disease. When a person with heart disease is given an EKG test, a 0.9 probability exists that the test will indicate the presence of heart disease.
Assume that all distributions are normal, the four population standard deviations are approximately the same, and the data were collected independently and randomly.
