For each of the following sets of numbers, calculate the sample size \((N)\), the mean \(\mathrm{X}^{-}\) , the standard deviation \((s)\), and the standard error of the mean \(s \mathrm{X}^{-}\):

a. \(4,5,8,9,11,11\)

b. \(27,19,14,25,19,22,26,23\)

c. \(2.7,3.1,3.4,2.1,2.8,3.3,3.0,2.9,3.8,3.1\)

d. \(12,10,9,11,9,15,10,9,8,13,9,10,7\)

e. \(11,9,20,12,10,19,7,8,23,14,34,9,17,6,14,19\)
