Data Analysis

          Our project is trying to determine if trawling effects the environment. One part of the project is testing water chemistry. Our group was trying to find out the difference in salinity in sleepy creek in summer and fall. We are also trying to determine the salinity in sleepy creek in the summer and the fall we accept the null hypothesis which mean there is no difference. For salinity in straits for summer and fall we rejected the null hypothesis. The salinity is higher in the summer.
