HypothesesHypotheses
Null Hypothesis- The golf balls will all Null Hypothesis- The golf balls will all travel the same distance and have the travel the same distance and have the same accuracy same accuracy
Alternate Hypothesis- The golf ball with Alternate Hypothesis- The golf ball with the most dimples will travel further and be the most dimples will travel further and be less accurate less accurate
