Find a new data set (can't be one of the ones posted before) with 15 - 20 observations.  Your data can be a single variable or you can compare two sets of data.  Tell what the data is for and where you got it.  Make a claim that the data is meant to test.  Your first response is simply to write the null and alternative hypotheses for someone else's data set.  Your second response is to use the null and alternative hypotheses created for the data set and to run a hypothesis test.  Your 2nd response post needs to include the sample mean, standard deviation, critical value (this should be from the t-distribution if it's not a proportion), standardized test statistic, and conclusion. (See the hypothesis steps listed in the formula sheet)
