a) A data is collected from Lab A. Sample mean is 12, SD is 2.4and sample size if 16. Another set of data from Lab B have a meanof 10 (assuming SDB is also 2.4 and nB=16).If we choose α = 0.05, do you think mean of Lab B is close enoughto be considered the “same†as that of Lab A? Why?
b) Same as problem 4), except SD of Lab B is SDB=4.4.If we choose α = 0.05, do you think the mean of Lab B is closeenough to be considered the “same†as that of Lab A? Why?
