1. Check the probability function of Problem 4-9 using the formulas of this section.
2. In rolling 3 dice, let X be the number of aces that occur. Tabulate the probatbility function of X. Find p and a2. Graph.
A student is given 4 questions, each with a choice of 3 answers. Let X be the number of correct answers when the student has to guess each answer. Compute the probability function and the mean and variance of X.
A company that manufactures computer chips wants to use a multiple regression model to study the effect that 4 different variables have on y, the total daily production cost (in thousands of dollars).
Verify that the significance level associated with the main effect for factor A is less than .001 but that you get a highly non-significant result for factor B and the hypothesis of no interaction.
a random sample of 10 items is drawn from a population whose standard deviation is unknown. the sample mean is 270 and

Free Throw Freddie is an 80% free throw shooter. At the end of practice he shoots until he makes 10 shots.
Write a Verilog description for a JK negative-edge-triggered flip-flop with clock CLK. Compile and simulate your description. Apply a sequence that causes all eight combinations of inputs J and K and stored value Q to be applied in some clock cycle..
Assume that you want to construct a 95% confidence interval estimate of a population mean. Find an estimate of the sample size needed to obtain the specified margin of error for the 95% confidence interval. The sample standard deviation is given b..
