A motor corporation advertisement read, "The average person's I.Q. is 107. The average brown trout's I.Q. is 4. So why can't people catch brown trout?" Suppose you believe that the brown trout's mean I.Q. is not four. You catch 12 brown trout. A fish psychologist determines the I.Q.s as follows: 5; 4; 7; 3; 6; 4; 5; 3; 6; 3; 8; 5. Conduct a hypothesis test of your belief. (Use a significance level of 0.05.)
