Two teaching methods for a statistics class, online and face-to-face, are available during the course of an academic year. To date, 1 out of every 25 students has failed the online class and 3 out of every 50 students have failed the face-to-face class. However, the online class is only offered 10% of the time due to faculty constraints and the face-to-face class is offered the other 90% of the time.

18. An insurance agent has claimed that the average age of policy-holders who insure through him is less than the average for all agents, which is 30-5 years. A random sample of 100 policy-holders who had insured through him gave the following age distribution : Age last birthday 16-20 21-25 26-30 31-35 36-40 No. of persons 12 22 20 30 16 : Calculate the arithmetic mean and standard deviation of this distribution and use these values to test his claim at the 5% level of significance. You are given that Z (1-645) = (0-95.
