1. Suppose that T has an exponential distribution with constant hazard 0.2.
(a) What is the probability that T‾ = 3?
(b) What is the error made if we approximate the probability that 2.5 ≤ T ≤ 2.75 by using the standard approximation?2. Consider the distribution with density function f (t) =β2te-βt, t ≥ 0. (This is a gamma distribution with first parameter 2.)
(a) Show that s(t) = (1 + βt)e-βt
(b) Find the hazard function μ(t).
(c) Describe precisely the shifted distribution T ? u. (Hint: It is a mixture of two well-known distributions.)

By usingu(x, t) = X(x)T(t) or u(x,y, t) = X(x)Y(y)T(t), separate the following PDEs into two or three ODEs for X and T or X, Y, and T. The parameters c and k are constants. You do not need to solve the equations.
For two samples from what are assumed to be normally distributed populations, the sample size and standard deviations are n1 = 10, s1 = 23.5, n2 =9 and s2=10.4.

During the last year sales averaged $22,000 per month. Does this indicate that monthly sales have changed (in a statistically significant sense)? Use 0.05. Assume monthly sales are normally distributed.
Preliminary results indicate that once a golfer has checked in, there is only at 20% chance that he or she will be a no-show. This chance of being a no-show can be modeled using the binomial distribution.
Consider the Xbar charts shown below for two processes. The charts may OR may not have instances of special cause variation. Identify ALL violation(s) (if any) of the eight tests where statistical signals show that special cause variation is ind..
