T-TEST FDR INDEPENDENT HEARS Two types of instruments for measuring the amount of sulfur monoxide in the atmosphere are being compared in an air pollution experiment It is desired to determine whether the types of instruments yield measurement having the same variability. The following readings were recorded for the instrument. Sulfur Monoxide Instrument A lnstrume nt B 0.86 0.8? 9.8 2 034.- .?5 0.63 {1.61 0.55 {1.89 0.?6 9.64 0.?0 {181 0.69 9.68 0.5? |{l'.65 0.53 Assuming the population of measurements to be approximately normally distributed, test the null hypothesis using twotailed test at 0.05 level ofsignicance. ONE SAM PLE T-TEST The pH factor is a measure of the acidity and alkalinity of water. A reading of H) is neutral; values in excess of Ti] indicate alkalinity; those below 7.0 imply acidity. In one study, it is mentioned that the best chance of catching bass occurs when the pH of the water is in the range 27.5 to 7.9. Suppose your suspect that acid rain is lowering the pH of your favourite shing spot and you wish to determine whether the pH is less than 15. You obtained 10 samples and got the following data: 7'3, '14, 7'2, "LU, T.5,?.4,?.3,?.3,?.2 and '11. test using 0.05 level of signicance. a. State the alternative and null hypothesis. b. Is the pH of the water samples less than 15
