A manufacturing company is testing the use of two different alloys in the formulation of solder. Test of the melting points (in oC) of solder formulations are undertaken using each different alloy. 50 tests are performed using each of the alloys and melting points are measured. The table below is for the sample statistics; Sample 1 (Alloy A) Mean = 210 Variance = 25 Sample 2 (Alloy B) Mean = 200 Variance = 16 i) Calculate the 95% confidence interval for the mean difference between solder formulations using two alloys. ii) What is the standard error (SE) of the mean difference in (i) above?
