the planning board members for a city are debating whether to build a new municipal parking garage. the parking garage would be funded by the revenue the city collects from its existing parking meters. since the board members insist that the parking garage cannot be funded by raising property taxes, the mean daily parking revenue collected must be greater than $1,200. a random sample of 35 days was selected, and the parking revenue collected in dollars was recorded. based on previous research, the board members assume that the population standard deviation is $196. the board conducts a one-mean hypothesis at the 1% significance level, to test whether the mean daily parking revenue is greater than $1,200.
