Answer:
y = 1.5x + 3.2009
Step-by-step explanation:
I plotted your points and drew a linear regression line.
Its equation is
y = 1.5x + 3.2009
The regression line ignores the fact that the points fall along a smooth curve.
A parabolic regression line fits the data much better.
The equation for that line is
y = - 0.1647x² + 4.1357x - 5.6946
It is the equation for a vertical parabola opening downward.
Answer:
200.131234
Step-by-step explanation:
Answer:
First, you would find the area of the trapezoid (I assume), then you would find the area of the circle. Then subtract the area of the circle from the area of trapezoid. Use the following equation:
Area of trapezoid - Area of circle
Answer:
The answer to the question is
μx + (σx/4)
Step-by-step explanation:
The sample mean that is one standard deviations above the population mean is given by
value = μx + (Number of standard deviations)
(σx/√n)
value = μx + 1 (σx/√16)=
= μx + (σx/4) =
Where
μx = Population mean
σx = Population standard deviation
n = Sample size
The standard error of the mean is
σ/√n =σ/√16 = σ/4
The standard of error is an indication of the expected error in the mean of a sample from the mean of the population.
The above statements is based on the central limit theorem, which states that, in particular instances the normalized sum of independent random variables becomes closer and closer to those of normal distribution regardless of the variation in the sample of the variables
