An economist wants to determine whether average Price/ Earnings (P/E) ratios differ for firm s in three industries. In dependent samples of five firms in each industry show the following results:
a. Construct an ANOVA table.
b. At the 5% significance level, determine whether average P/E ratios differ in the three industries.
c. If differences exist, use Tukey's text at the 5% significance level to determine which industries' mean P/E ratios differ.
That is, P (X = x1|θ1) = 0.1 or P (X = x2|θ3) = 0.4, and so forth. Suppose you observe X1; what is the updated prior? What is the Bayes decision?
An averageof 2 cars arrive at a highway tollgate every 10 seconds. If this rate is approximated by a Poisson process, what is the probability that exactly 3 cars will arrive in a 10-second period?
