Table 7 SD Variance Pipette Procedure First Stop Lot 32 g Second Stop (show your work) 3. Step 2. Calculate the t-statistic 4. Step 3 a) Degrees of Freedom b) Let a 0.05 c) Table value for t-statistic is: d) State the Region of Rejection 5. Step 4. State your conclusion for this analysis. Please write sentences in plain English explainin why you reject or don't reject your null hypothesis, and what that means about a significant difference between the mass measured by the two methods. 6. Step 5. Bracket the p-value.Explanation / Answer
Considering that the pipetting at each step has been done atleast thrice
The two-tailed P value is less than 0.0001
By conventional criteria, this difference is considered to be extremely statistically significant.
Two-tailed means the results can tend towards any direction and therefore is more stringent.
Degress of freedom is 4 and t = 26.7477
Null hypothesis is rejected since the p value is highly significant i.e.<0.05, which is the end point criteria.
