Two types of instruments (Instrument A and instrument B) 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. Based on a random sample of readings recorded for cach of the two instruments, they found a 90% confidence interval for the ratio of the variance for Instrument A to the variance for Instrument B to be (0.016, 0.454). Based on this interval, what conclusions can the researchers make? Since 1 is in the interval therance are not significantly different O Since the upper limit is below 1. the variance for instrument A is signifiquntly greater than that for instrument B. Since the upper limit is below 1. the variance for instrument B is significantly greater than that for Instrument A Since O is not in the interval, the variances are significantly different
