The procedure for constructing a confidence interval about a mean is which means minor departures from normality do not affect the accuracy of the interval

Robust is the procedure for constructing a confidence interval about a mean, which means minor departures from normality do not affect the accuracy of an interval.
The robust confidence interval has a theoretical guarantee on having coverage, it also used to identify the sensitivity of inference when instrumental variable assumptions are violated.

Yes, two vertical lines can be complementary

Answer:

$4034.40

step-by-step explanation:

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
