Descriptive and Inferential Statistics. Provide univariate descriptive statistics and appropriate plots for the training data set. Provide a scatterplot matrix for at least two of the independent variables and the dependent variable. Derive a correlation matrix for any three quantitative variables in the dataset. Test the hypotheses that the correlations between each pairwise set of variables is 0 and provide an 80% confidence interval. Discuss the meaning of your analysis. Would you be worried about familywise error? Why or why not?

A deck of ordinary cards is shuffled and 13 cards are dealt. What is the probability that the last card dealt is an ace?
The Acme Super light bulb is known to have a useful life described by the density function
f(t)=.01e−0.1tf(t)=.01e−0.1t
Where t is measured in hours.
A) Find the failure rate of this bulb (see Exercise 2.2.6)
B) Find the reliability of this bulb after 20 hours.
C) Given that it lasts 20 hours, find the probability that the bulb lasts another 20 hours.
D) Find the probability that the bulb burns out in the forty-first hour, given that it lasts 40 hours.
