Recently gasoline prices rose drastically. Suppose that a study was conducted using truck drivers with equivalent years of experience to test run 24 trucks of a particular model over the same highway. Estimate the population mean fuel consumption for this truck model with 90% confidence if the fuel consumption, in miles per gallon, for these 24 trucks was as follows:15.5 21.0 18.5 19.3 19.7 16.9 20.2 14.516.5 19.2 18.7 18.2 18.0 17.5 18.5 20.518.6 19.1 19.8 18.0 19.8 18.2 20.3 21.8The data are stored in the data file Trucks.

Question
Recently gasoline prices rose drastically. Suppose that a study was conducted using truck drivers with equivalent years of experience to test run 24 trucks of a particular model over the same highway. Estimate the population mean fuel consumption for this truck model with 90% confidence if the fuel consumption, in miles per gallon, for these 24 trucks was as follows:
15.5 21.0 18.5 19.3 19.7 16.9 20.2 14.5
16.5 19.2 18.7 18.2 18.0 17.5 18.5 20.5
18.6 19.1 19.8 18.0 19.8 18.2 20.3 21.8
The data are stored in the data file Trucks.
