Jul 02, 2010 · The equation is μ = x(bar) ± (t ∙ s)/ √n . First we need the mean and standard deviation. Learn to use your calculator or Excel to get these values. You should get x(bar) = 0.148 and s = 0.034. Since we have 6 values, the degrees of freedom is N – 1 = 6 – 1 = 5. We get the values of t from Table 4-2. For a 90% confidence level, t = 2.015.
