2. Two types of instruments for measuring the amount of sulfur monoxide in the atmosphere are being compared in an air-pollution experiment. Researchers wish to determine whether the two types of instruments yield measurements having the same variability. The readings in the following table were recorded for the two instruments. Sulfur Monoxide Instrument A Instrument B 0.86 0.82 0.75 0.87 0.74 0.63 0.55 0.76 0.70 0.61 0.89 0,64 0.81 0.69 0.57 0.53 0.68 0.65 Assuming the populations of measurements to be approximately normally distributed, test the hypothesis that ƠA = OB against the alternative that ơA + OB. Use a 0.05 level o significance
