In order to be sure that the sample mean does differ from the population mean by more than 0.90, the sample size (n) that should be used is given by:

Where 'Z' , for a 95% probability is 1.960, 's' is the standard deviation of 2.5 inches:

Rounding up to the nearest whole number, the sample size should be at least 30 men.

Answer:
(f×g)(2) = 3/4
Step-by-step explanation:
For each of the functions, put 2 where x is and evaluate the expression.
f(2) = (3 -2)/(2² +4) = 1/8
g(2) = 3×2 = 6
Then the product is ...
(f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8
(f×g)(2) = 3/4
