The Iowa Department of Transportation repaired hundreds of bridges in 1993. To check the average cost to repair a bridge, a random sample of n-55 bridges was chosen. The mean and standard deviation for the sample are $25,788 and $1,540, respectively. Records from previous years indicate an average bridge repair cent was $25,003. Use the sample data to test that the 1993 mean is greater than $25,003 Use -0.05. What is the null and alterate hypothesis?
