(4) [14 pts] Grades on a standardized test are known to have a mean of 1000 for students in Canada. The test is administered to 453 randomly selected students in Alberta; in this sample, the mean is 1013 and the sample standard deviation is 108. (c) Another 503 students are selected at random from Alberta. They are given a 3-hour preparation course before the test is administered. Their average test score is 1019 with a standard deviation of 95. (i)...
