The US divorce rate has been reported as 3.6 divorces per 1000 population. Assuming that this rate applies to a small community of just 500 people and it’s Poisson distributed, and that x = the number of divorces in this community during the coming year, determine the following : a. E(x) b. P(x=1) c. P(x=4) d. P(x6) e. P(2x5)

2) A study was conducted to examine four methods for tutoring in mathematics. Four studentswere randomly assigned to each method, and a pretest score (x1) was obtained before tutoringbegan. The response of interest is a posttest score (y), and dummy variables x2, x3, and x4, werecreated for methods 1, 2, and 3, respectively. Variables x5, x6, and x7, are crossproductvariables for methods 1, 2, and 3, respectively, multiplied by x1. The results from fitting threeregression models to these data are attached to the end of the exam. Since the posttest score isharder than the pretest, it is not unusual for x1 values to be higher than y values. a) Assuming that the parallelism assumption is valid, test for equality of the adjustedgroup means, using alpha = .05. Write the null and alternative hypotheses, calculate an F statisticvalue, compare it to a tabled value and state your conclusion from the hypothesis test. b) Use the fact that the sample mean of x1 is 4.44, and the printout from…
