The pewa Department of Transportation repaired hundreds ofbridges in 2916. To check the average cost to repair a bridge, arandom sample of n = 55 bridges was chosen. The mean and standarddeviation for the sample are $36,788 and $1,540, respectively. Records from previous years indicate an average bridge repair costwas $35,003. Use the sample data to test that the 1993 mean μ is greater than $35,003. Use α = 0.06. What type of test would be used?
