Estimates Made Using Sx Two different statistical estimates can be made using Sx. [1] the value of the next sample value, xi, where [2] the value of the true mean, x‘, where

Example 8.5 [1] p range that contains the next measurement with P = 95 % [2] same but for N = 5 [3] for N = 19 and P = 50 % [4] p range that contains the true mean

Using MATLAB® The command tpdf(t,n) gives the value of p(t). The command tcdf(t*,n) gives The command tinv(P,n) gives t* from the cdf. The command tinv([1-P]/2,n) gives -t. The command tinv([1+P]/2,n) gives +t.
