I believe also 115 degrees bc they’re vertical angles
The domain is y >=0. Domain is the possible x values
I think it is acute because below 90 is acute above 90 is obtuse and exactly 90 is right
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."
