Question

Identify Ho and Ha for a paired t-test to determine if there is a difference in the number of breeding horseshoe crabs from 2011 to 2012:

 The mean difference between paired observations is zero.

 The mean difference between paired observations is not zero.

Use the paired t-test function (=ttest(array1, array2, tails, type) to determine the if the two sets of measurements are correlated with each other.

Report your answer to three decimal places. 

Do you fail to reject or reject the null hypothesis? 

Were the number of breeding horseshoe crabs the same or different between between the two years?
