Students performing vinegar analyses made several mistakes in their experiments. Explain in detail how each error below will affect the final result (% weight of acetic acid in vinegar) of each student's experiment. Show all steps of logic followed in analyzing the effects of the mistake (remember that the experiment had two parts):

1.Student A used a wet beaker to transfer the NaOH solution to be standardized from its original container to the buret.

2.Student B did not fill the tip of the buret with titrant before starting the NaOH standardization, so the tip contained air when the titration was started, but was filled after the first standardization.

3.Student C over-titrated the php solution, but ignored it and continued on with calculations.

4.Student D was in a hurry to leave the lab. He finished the titration of vinegar without waiting for the pink color to persist for 15 seconds. He recorded the volume of NaOH used, just to notice that the pink color disappeared. He ignored this observation and proceeded with calculations.

A chemist is performing four experiments and each experiment has five results. The results for each experiment are given in the following table. An experiment is considered successful if the average of the five test results for a given experiment is between 25 and 32. Using a nested loop, write a script that (Python): - Compute and display the test results average for each experiment - Indicate is the experiment was successful or not 1st Results 49.1 15.8 16.9 25.2...

Each of the following statements contains an error. Describe each error and explain why the statement is wrong. (a) If the residuals are all negative, this implies that there is a negative relationship between the response variable and the explanatory variable. (b) A strong negative relationship does not imply that there is an association between the explanatory variable and the response variable. (c) A lurking variable is always something that can be measured.
