Two types of instruments for measuring the amount of sulfur monoxide in the atmosphere are being compared in an air-pollutant experiment. It is desired to determine whether the two types of instruments yield measurements having the same variability. The following readings were recorded for the two instruments:


Instrument A

Instrument B

0.86

0.87

0.82

0.74

0.75

0.63

0.61

0.55

0.89

0.76

0.64

0.70

0.81

0.69

0.68

0.57

0.65

0.53

Assuming the population of measurements to be approximately normally distributed, test the hypothesis that using classical and p-value approaches using 0.10 level of significance.
