The value of Z-Statistics, computed front a sample having n = 16, \(\overline{x}=24\) for testing H0; μ = 23, when population standard deviation (σ) = 8, is:

3.5 1.2 1.8 0.5

0.5

\(Z=\frac{\overline{x}-Δ}{\frac{σ}{\sqrt{16}}}\); $\overline{x}=24$, n = 16, H0; μ = 23, σ = 8 \(Z=\frac{24-23}{\frac{8}{\sqrt{16}}}=\frac{1}{\frac{8}{4}}=\frac{4}{8}=\frac{1}{2}=0.5\)
