#Question
Null hypothesis; mean of experiment = mean of control
Observed t-statistic from Excel = -0.134
Critical t-value for this research question = 2.228
Conclusion: from the data above, the t-statistic value does not lie between -2.228 and 2.228
Therefore, we fail to reject the null hypothesis.

#Questions
Null hypothesis; Mean of year 1 = Mean of year
Observed t-statistic from the data above in Excel = -2.37
The critical t-value from this research = 2.015
Conclusion: since t-value(-2.37) does not lie between -2.015 and 2.015 we reject the null hypothesis
