Data Analysis

           Is the number of fish that were caught in Sleepy Creek in the fall different than the number of fish caught in Straits?  We used a statistical t-test to analyze our data. We found that there was no difference in the number of fish caught in Straits and Sleepy Creek.  We did accept the Null Hypothesis.  The number of fish that was caught in Sleepy Creek closed was just 1 which was 21 from the amount of fish caught in Straits open that was 20.  In the fall and summer combined we rejected the Null hypothesis.  The number of fish that were caught in Sleepy Creek was 95.1 and in Straits was 39.  The Null hypothesis states that there is no difference but we proved it to not be true.
