RSD calculation
In this problem, you will determine the % relative standard deviation (%RSD) from a series of titrations. Pretend that the [NaOH] you measured in your three titrations are 0.1018, 0.0962, and 0.1010. Determine the %RSD of these three values. Write your answer to one decimal place.

In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. Consider the data set 5, 9, 7, 11, 4. (a) Use the defining formula, the computation formula, or a calculator to compute s. (Round your answer to one decimal place.) (b) Multiply each data value by 4 to obtain the new data set 20, 36, 28, 44, 16. Compute s. (Round your answer to one decimal...

One hundred teachers attended a seminar on mathematical problem solving. The attitudes of representative sample of 12 of the teachers were measured before and after the seminar. A positive number for change in attitude indicates that a teacher's attitude toward math became more positive. The twelve change scores are as follows. 3; 9; −1; 2; 0; 4; −3; 1; −1; 5; 4; −2 Part (b) What is the standard deviation for this sample? (Round your answer to two decimal places.)...

F-Test and corresponding t-Test for 95% confidence Three different methods were used to deterrmine the concentration of a certain bulk solution af acetic acid. The three methods were all titrations, using the same standard NaOH solution as titrant, and identical volumetric technique. The only difference was the choice of acid-base colour indicator to reveal the endpoint. For each method, the average acetic acid concentration and its standard deviation for the number of titrations (n) performed are summarized below IndicatorCH,COH+S (M)...
