I need help with conducting a hypothesis test to determine whether the mean miles traveled last month equals 10,000. I will be using a .01 significance level, and need to find the P-value and explain it..

Mean miles is 11120.43

Also need to conduct a hypothesis test to determine whether the mean maintenance cost for bus fleet is more than $4,000 at the .05 significant level and determine the p-value?

Maintenance cost is 4551.89

I don't want the answer but how to figure it out through excel and get the answer on my own.
