(Solved): Can sombody please help me with part 2, both questions 1 and 2? Part 2 - Statistical Interpretation ...

Part 2 - Statistical Interpretation of Micro-pipette Exercise During your lab period you pipetted the same volume of solution into centrifuge tubes using two dispense methods. The first method was to the micropipette's $2^{\text{nd }}$ stop (the accurate method), whereas the second was only to the micropipette's $1^{\text{st }}$ stop (the inaccurate method). The weight ( $\mathrm{g}$ ) of the solution was compared to see if there was a significant difference. The statistical summary is below: $t$-test statistic $=?4.31,df=144,p=0.0003$. The mean weight of solutions using a micropipette to the second stop was $0.784\mathrm{g}$, and the mean weight of solution using a micropipette to the first was $0.689\mathrm{g}$. Answer the following: 1. Which pipette method yielded the greater volume (measured by weight)? 2. What can you conclude about the differences in volume (solution weights) between the two methods? - What the statistical null hypothesis for this experiment is. - What the statistical alternative hypothesis for this experiment is. - Which statistical hypothesis does the statistical results support?
