I'm working on a problem and was hoping I could get either confirmation that I'm doing it correctly, or help in learning the correct way. I used Excel to calculate a stock's Beta, comparing percentage changes in the stock price to that of the S&P 500. I am now tasked with implanting a hypothesis test testing whether the population Beta is greater than 1. My understanding of how to work this problem is that I will subtract 1 from my regression coefficient, and then divide that by the standard error of the regression coefficient to arrive at my t-statistic. I will then use a one tail t-test to arrive at my p-value. Is this correct? If not, how would I go about conducting this test? Thank you very much for your time and help.
