...) A trucking fleet-owner owns two semi-trucks and wishes to compare the amount of fuel used per week by the two vehicles. In a random sample of 100 weeks, truck #1 used a mean volume of 320 gallons with a standard deviation of 11 gallons. In a second, independent random sample of 100 weeks, truck # 2 used a mean volume of 316 gallons with standard deviation 7 gallons. t is of interest to construct a confidence interval for the difference in population means using a confidence level of 90 percent. ₁-2, where is the mean fuel volume used by truck #1 and 2 is the mean volume of fuel used by truck #2. Note: and Enter values below rounded to three decimal places. a) The estimate is: b) The standard error is: c) The multiplier is: gallons. gallons. 3203164 11² 7² V100 100 + = 1.30384048104053
