city council is deciding whether or not to spend additional money to reduce the amount of traffic. The council decides that it will increase the transportation budget if the amount of waiting time for drivers exceeds 18 minutes. It decides to collect sample data a hypothesis test of the wait times. Waiting times were recorded for a sample of 28 main roads and the sample mean and sample standard deviation were computed. The sample statistics were used to compute a test statistic of 1.59. (a) Give the p-value (Round to three decimal places.) (b) State whether or not the city should increase its transportation budget, at the 5% significance level. Explain briefly.
