600 every 10 years is the right answer
95% C.I. = mean + or - 1.96(standard deviation / sqrt(sample size))
95% C.I. = 57 + or - 1.96(3.5/sqrt(40) = 57 + or - 1.085 = 57 - 1.085 to 57 + 1.085 = 55.92 to 58.09
Therefore, 95% of the mean will occur in the interval 55.92 to 58.09
5.
You could do 3 x 3 x 5 x 5 for perimeter, so the area is 3 x 5.
The answer therefore, is 15 ft²
