Hi,
See the data set below.
Based on this, Excel comes with the following analysis (paired

I need to calculate a 95% confidence interval. Based on this, I
came to the following formula: [Mean of the difference (D-mean) +/
t(alpha/2) * Sd / sqrt(n)]. I can fill in the following
information:
D-mean = 27-34 = -7.
t(alpha/2) = 2,262
sqrt(n) = sqrt(10)
Do you now how I can find the standard deviation of the sample?
