A researcher is conducting a matched-pairs study.She gathers data on each pair in the study resulting in:  Assume that the data are normally distributed in the population.The sample standard deviation (s)is ___.
A)1.3 
B)1.14 
C)1.04 
D)1.02 
E)1.47

To calculate the sample standard deviation, we can use the following formula: s = sqrt(sum((x-mean)^2)/(n-1)). 
Using the given data, we can calculate the mean to be 11.27. 
Then, plugging in the data and calculating, we get s = 1.14.
