The researchers analyzed the data and obtained the following output: Summary statistics: Sample n Mean Variance Std. Dev. Std. Err.

Thus, the researchers conclude that 6th grade students get, on average, fewer correct answers and, thus, lower scores on math tests when taking them under timed conditions as compared to untimed conditions. the data provide sufficient evidence to reject H0. Thus, based on the data the researchers cannot conclude that mean number of correct answers on the math test for the Timed Condition is lower compared to the Untimed Condition. The data do not provide sufficient evidence to reject H0.
