Problem 6: Suppose we observe a random variable X having a binomial distribution with parameters n and zp. (a) What is the generalized likelihood ratio for testing Ho : p-0.5 against H, : p* 0.5? (b) Show that a generalized likelihood ratio test rejects Ho when |X -n/2|2 c. (Hint: it may help to consider the logarithm of the generalized likelihood ratio.) (c) What is the significance level of the test when n 12 and c 5?

(Refer to HW6 #2) Rural and urban students are to be compared on the basis of their scores on a nationwide musical aptitude test. Two random sample of sizes 90 and 100 are selected from rural and urban seventh grade students. The summary statistics from the test scores are Rural Urban Sample size 90 100 Mean 76.4 81.2 Standard deviation 8.2 7.6 Do these data provide strong evidence that there is a difference in population mean scores between urban and...

Problem 1 A student decided to perform at 5% sigfnificance level usual t-test for H:4=3 against H:4 3, for a sample of size n=10. But she did a mistake: used wrong degrees of freedom df - 10 instead of correct df - 11-1-9, so she used wrong critical value. What is the probability of type I error that she would have performing the test? Problem 2 Let X is amount of coffee in a "100g coffee can", EX = 4....
