Hello!
75 + 90 + 79 + q = 360
q = 360 - 244 = 116
Stay safe!
Answer:
the populations from which the samples were drawn have different standard deviations
Step-by-step explanation:
Given that the assumption of homogeneity of variance is the same as the assumption of the independent samples t-test which asserted that all comparison groups possess the same variance
Therefore, if the homogeneity of variance assumption is violated in an independent groups t-test, this means "the populations from which the samples were drawn have different standard deviations."
Answer:
In y = kx, where k is the constant of proportionality.
Answer:
See explanation
Step-by-step explanation:
Given two expressions:
and
a. When 
then
and
b. When 
then
and
c. Since the value of both expressions at s = 12 are different, the expressions are not equivalent.
Looking at the figure, we can see that both triangles are right triangles. Therefore, we can apply pythagorean theorems. A right triangle contains a hypotenuse, which is the longest side. In the figure, that would be sides with length 4 and 12. The equation for this is:
c = √(^2 + b^2) , where c is the hypotenuse and a and b are the other shorter sides
To determine z:
4 = √(z^2 + 3^2)
z = 2.65
To determine x:
12 = √(x^2 + 6^2)
x = 10.39
