QUESTION 1.5.<br>A report by the Gallup Poll found that a woman visits her doctor, on average, at most 5.1 times each year. A random sample of 20 women results in these<br>yearly visit totals<br>> x<-c (3,2,1,3,7,2,9,4,6,6,8,0,5,6,4,2,1,3,4,11)<br>i) At the a = 0.05 level can it be concluded that the sample mean is higher than 5.1 visits per year? Assume the counts are Poisson distributed,<br>P(5.1). ii) What is the probability of type II for this test, when the true mean is 5.8?<br>
