A Nissan Motor Corporation advertisement read, "The average man's I. Q. is 107. The average brown trout's I. Q. is 4. So why can't man catch brown trout?" Suppose you believe that the brown trout's mean I. Q. is greater than 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.)

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
