How do you get the value of y intercept in least squares method?
To find the y-intercept, you need to calculate the gradient, b. Then a, the y-intercept, satisfies the equationy-bar = a + b*x-barwhere x-bar and y-bar are the means of the two variables.
What are the control limits for mean and range?
You will need to calculate the grand mean (x double bar) and r bar. From those values and the chart for the constants, all listed in the related link, you will be able to calculate the control limits.
How to calculate surface area of flat bar?
If the bar is a three dimensional object it will have some thickness. Then, assuming it is oblong in shape and knowing its length, width and thickness: Surface_area = 2 x (length x width + width x thickness + thickness x length)
How many one inch cubes are there in a three inch cube?
You calculate this as 3 x 3 x 3 = 27.You calculate this as 3 x 3 x 3 = 27.You calculate this as 3 x 3 x 3 = 27.You calculate this as 3 x 3 x 3 = 27.
Which measure of central tendency does x-bar represent?
X-bar represents the mean or average of the sample variable.
