b) Victor and Wilfred arrive at a railway station independently

Question b) Victor and Wilfred arrive at a railway station independently of one another at a random time between 1pm and 2pm. Let V be the number of minutes past 1pm when Victor arrives, and let W be the number of minutes past 1pm when Wilfred arrives. The marginal density functions of V and W are both uniform: 1 fv(v) = fw(w) = 60 , 0 ‘.S V < 60, 0 '.S W < 60. i) Briefly explain ( one sentence only is required) why the joint density function of arrival times of Victor and Wilfred is 1 fv,w( v, w) = 3600' 0 '.S V < 60, 0 '.S W < 60. ii) Using fv,w(v, w), or otherwise, determine the probability that Victor arrives before Wilfred, i.e find P(V < W). iii) Let T = W – V be the time (in minutes) between Victor's arrival and Wilfred's arrival. A) Determine the cumulative distribution function Fy(t). B) Hence, or otherwise, determine the density function jy(t).  ATTACHMENT PREVIEW Download attachment IMG-0335.JPG

Question We wish to estimate p, the chance of obtaining a head when a particular coin is flipped. To do so, the coin is randomly flipped many times. For i = 1, … , let Xi = 1 if a head is obtained on the ith flip and Xi = 0 otherwise. The Xi are i.i.d. Bernoulli(p) random variables for some 0 < p < l and the probability function can be given by P(Xi = x) = f(x) = {P 1-p or equivalently by for X = l for X = 0 for X = 0, 1. Suppose the coin is to be flipped n times, resulting in observations x1, x2, . .. , Xn, The sample proportion of heads can be computed by p = I::~o Xi = x. n a) Determine the method of moments estimator of p. Show that it is given by the sample proportion p. b) Determine the maximum likelihood estimator of p. Show that it is given by the sample proportion p. c) Determine the Fisher information for p. d) i) Write down the large sample approximation to the distribution of p. ii) Use the delta method to deduce the large sample approximation to the distribution of 1fJ .. -p e) Assume now that the coin is flipped n = 100 times, and that a head is obtained 75 times in the 100 flips of the coin. Compute an (approximate) 95% confidence interval for p.  ATTACHMENT PREVIEW Download attachment IMG-0340.JPG

Imagine data that showed the number of violent crimes per

Question Imagine data that showed the number of violent crimes per year and the number of churches (of all denominations) in 100 U.S. cities. Research has shown that these two variables are highly correlated; that is, cities that have more churches also tend to have a larger number of violent crimes, and cities with fewer churches tend to have fewer violent crimes. Does this result mean that churches cause crime, or that crimes cause churches to be built? Based on this information, what can we conclude about the relationship between these two variables? What else might be going on to make up this relationship?

Question The council decides to perform a water quality check every day. This test costs $500 each day. If a pollutant is found in the water, they assume that they will find the pollutor, and they will fine them $50,000. What does the probability to find a pollutant in the sample each day at least have to be, for the council to be 90% sure that they will not lose money on these tests, in a non-leap year?
