Test II. Use the standard normal distribution table to nd the following z-scores. Illustrate the normal curve. 1. Find the following z-scores when the mean is 25 and the standard deviation is 4: (3pts each) a. 20 b. 32 c. 28 d. 25 e. 17 2. The average rate per hour of an employee in a fastfood chain is Php38 with a standard deviation of 5. If these values were normally distributed, (5pts each) a. What percent of the employees got an hourly rate of 40 and above? b. What percent of the employees got an hourly rate between 30 and 40? c. If there were 200 employees, how many got an hourly rate of above Php43? Test III. Please follow steps in testing hypothesis. 1. A diet clinic states that there is an average loss of 24 pounds for those who on the program for 20 weeks. The standard deviation is 5 pounds. The clinic tries a new diet, reducing salt intake to see whether that strategy will produce a greater weight loss. A group of 40 volunteers loses an average of 16.3 pounds each over 20 weeks. Should the clinic change the new diet? Test at o=.05(20 pts)
