This is the dataset of the difference between after treatment lab scores and before treatment lab scores. alfa(significance level) is 0,05.

question ) You suspect that the treatment has decreased their lab scores. Conduct a hypothesis test
to see if the lab score has decreased significantly. (minus means it is decreased)
