The data was collected under a paired design. You will need to carefully check how the experiment was done or the survey was done. If you don't reject the null hypothesis, then power and sample size considerations are important. JMP can help you do this. Seek help from a statistician for further assistance.
Hand formula are available for all the computations, but who cares.
If you are given only the summary statistics, you may have a problem unless you are also given the summary statistics for the differences. Seek help from a statistician. It is possible to have a missing value for one of the values in pair. It is possible for the confidence interval for the difference to contain the value of 0 and a one-sided test reject the hypothesis. The reason is that a confidence interval is like a two-sided test.
