Q3)An experiment is carried out to test the effect on fuel consumption of three fueladditives B and C. C is the current standard additive and B is new. The same driverdrives the same car on a fixed test route during 20 working days. The additive B and Care used for 10 days each. The number of miles per gallon (mpg) measured each day isshown in the following table.Additive B39, 36, 37, 35, 38, 36, 41, 39, 39, 40Additive C37, 35, 36, 31, 34, 33, 34, 34, 36, 30Assuming that the population variances are equal, test at the 0.05 level of significance,whether there is a significant difference in fuel consumptions between B and C.

The random variable is fuel consumption. There are two independent samples which are additive B and…

T-TEST FOR INDEPENDENT MEANS 1. 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 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 null hypothesis using two tailed test at 0.05 level of significance.
