For each of the following situations, calculate the \(z\)-statistic \((z)\).

a. \(\mathrm{X}^{-}=14.00 ; \mu=11 ; \sigma=6 ; N=36\)

b. \(\mathrm{X}^{-}=7.00 ; \mu=8 ; \sigma=3 ; N=9\)

c. \(\mathrm{X}^{-}=2.86 ; \mu=2.69 ; \sigma=.40 ; N=29\)

d. \(\mathrm{X}^{-}=10.12 ; \mu=7.98 ; \sigma=4.59 ; N=26\)

e. \(\mathrm{X}^{-}=92.87 ; \mu=101.55 ; \sigma=20.65 ; N=43\)
