Two of your friends at School A and School B heard that you are taking a statistic course and would like your help with their chemistry lab reports. They both have 10 independent measurements of the specific gravity of a compund from different populations. Their results are:  School A 4.50 3.82 3.50 3.93 3.35 3.65 3.67 3.44 3.20 3.80 School B 5.10 4.34 2.40 4.90 1.23 3.89 1.87 5.30 4.65 4.70 They would like to know whether the data show convincingly that there is a significant difference between the two report given a Significance level of 1%. What is your conclusion?
