Answer:
Affects the width of a confidence interval, as the margin of error is a function of the sample standard deviation.
Step-by-step explanation:
When we have the standard deviation for the sample, the t-distribution is used to solve the question.
It does not affect the center of the interval, which is a function only of the sample mean.
Width of a confidence interval:
The width of a confidence interval is a function of the margin of error, which is:
In which s is related to the sample standard deviation. Thus, since s and M are directly proportional, a higher standard deviation makes the interval wider, lower standard deviation makes the interval narrower, and thus, the sample standard deviation affects the the width of a confidence interval.
Given:
Length = 3x + 6y cm
Area = 3x² + 9xy + 6y²
Because Area = Width * Length, therefore
Width = Area/Length
= (3x² + 9xy + 6y²)/(3x + 6y).
Width =
Answer: x+y
Length = 3x + 6y cm
Area = 3x² + 9xy + 6y²
Because Area = Width * Length, therefore
Width = Area/Length
= (3x² + 9xy + 6y²)/(3x + 6y).
Width =
Answer: x+y
