Step 3: Interpret the output

The following are the null and alternative hypotheses for the paired t-test.

Null Hypothesis: Writing and Reading are not different.

Alternative Hypothesis: Writing and Reading are different.

The mean for reading is 52.23 and the mean for writing is 52.78. The P-value of 0.387 is greater than 0.05. That means that we failed to reject the null hypothesis. Therefore, we conclude that writing and reading scores are not significantly different.
