1 : A data is collected from Lab A, and this data is considered as the reference (standard). Sample mean is 10, SD is 1.8 and sample size if 25. Another set of data from Lab B have a mean of 8, SDB is 1.4 and nB=24. If we choose = 0.05, do you think mean of Lab B is close enough to be considered the "same" as that of Lab A? Why? Show working Question 2 : Same as problem 4, except SD of Lab A is SDA=2.8. If we choose = 0.05, do you think the mean of Lab B is close enough to be considered the "same" as that of Lab A? Why?
