Question: Consider the following data set. The data were actually collected in pairs, and each row presents a pair.

  1. Suppose that we ignore the fact that the data were collected in pairs and mistakenly treat this as a two-sample problem. Compute the sample mean and variance for each group. Then compute the two-sample t statistic, degrees of freedom, and p-value for the two-sided alternative.
  2. Now analyze the data in the proper way. Compute the sample mean and variance of the differences. Then compute the t statistic, degrees of freedom, and P-value.
  3. Describe the differences in the two results.
