Raquet brand, Sample size, Sample Mean, Sample St. deviation
Prince 150, 980, 1.5
Head 150, 1005, 2
1. Does the data provide compelling evidence for concluding that true average power for the Head raquet is different that the power for the Prince raquet? Test the appropriate hypotheses using the P-value approach and the Rejection Region
2. Does the data provide compelling evidence for concluding that true average power for the Head raquet exceeds that for the Prince power by more than 20 ? Test the appropriate hypotheses using the P-value approach.
3. Calculate a 92 and 95, and 97% Confidence interval for the true average power of the two requests
