A certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 6 students' scores on the exam after completing the course:1, 14, 16, 14, 14, 3Using these data, construct a 90% confidence interval for the average net change in a student's score after completing the course.

please show working out. Thank you A University has put in place a 4 week course of lunchtime exercise breaks for its staff to see if its employees’ job satisfaction can be improved. To measure the effectiveness of this program, 10 randomly selected staff in the program were surveyed about their feelings at work, once at the start of the program and again after the course. Higher scores indicate higher satisfaction. The job satisfaction index results for this group were: Staff 1 2 3 4 5 6 7 8 9 10 Before 34 28 29 45 26 27 24 15 15 27 After 33 31 36 46 32 34 28 26 19 37 Use a test of significance at 5% level to decide if the program has improved the employee’s job satisfaction on average. Show your graphical evidence, if needed, and clear conclusion. - please sketch the curve as well. thank you
