In an experiment to compare the tensile strengths of I = 6 different types of copper wire, J = 5 samples of each type were used. The average between group and average within group estimates were computed as MSTr = 2616.3 and MSE = 1106.2, respectively. Often hypothesis tests are conducted using what is referred to as the rejection region method. This compares the calculated F test statistic to an F value that cuts off a "rejection region". If the calculated test statistic falls within the rejection region, the null is rejected. The F value that represents the cut off for the rejection region, is the F value that cuts off the top α% of area in an F distribution with I-1 and I(J-1) degrees of freedom. In other words, if α = 0.05, the F rejection region cut off will be the 95th percentile from the appropriate F distribution.

answering the question, i caught myself thinking that I was insanely excited, do you want to have some fun?

waiting for you <3

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
