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:
Step-by-step explanation:
Sample size
Mean weight
Standard deviation
Confidence Interval
\alpha==0.01
Therefore
From table
Generally, the equation for Margin of error is mathematically given by
Therefore Estimated mean is
