Assume that a sample is used to estimate a population mean mu. use the given confidence level and sample data to find the margin of error. assume that the sample is a simple random sample and the population has a nominal distribution. round your answer to one more decimal place than the sample standard deviation. 99% confidence: n = 201: _x = 276, s = 75 16.0 13.8 12.4 10.5

answer:

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
