A bus company is doing research to determine if it can save money by switching from gasoline-powered buses to electric-powered buses. The company randomly selects records of gasoline usage from 30 days and calculates that the buses use a mean 22 gallons of gas each day with a standard deviation of 1.8 gallons. The gas station the buses use charges $2.95 for a gallon of gas. The company also knows it would cost $62 to charge the buses enough to be able to run for one day. Use a 95% confidence interval to recommend a strategic decision for the bus company. The bus company should switch to the electric buses because 22 gallons of gas costs more than $62. The bus company should switch to the electric buses because the least amount of mean gas per day in the confidence interval costs more than $62. The bus company should not switch to the electric buses because the least amount of mean gas per day in the confidence interval costs less than $62. The bus company should not switch to the electric buses because the greatest amount of mean gas per day in the confidence interval costs less than $62.
