I need your help. Thanks!!

Sher Jangal is a golf instructor. He claims that with just one lesson from him, he can improve a client's driving distance (how far one can hit the ball from the golf tee). We took a sample of 9 of his students and measured their driving distance before and after one lesson with Sher Jangal. The following data was collected. Driving Distances (in metres) of Sher Jangal's Clients before and after one lesson with him Client 2 3 5 6 7 8 Before 104 224 220 226 162 204 138 162 113 After 109 224 232 224 168 212 142 172 124 Difference, d (After - Before) 5 0 12 -2 10 11 The differences (After - Before) in this sample had an average of 6.0 m, with a standard deviation of 4.8 m. At the 1% significance level, is there enough evidence to conclude that one lesson with Sher Jangal will increase a client's mean driving distance?
