Hоur-lоng TV shоws run аn аverаge of 48.8 minutes, excluding commercials. A sample of 51 recent shows had an average of 47.6 minutes with a standard deviation of 3.16 minutes. At α = 0.025, determine whether the true value is lower than originally thought. What is the df? Report your answer as a whole number.
