Short Answer

In testing the hypotheses: $H _ { 0 } : \mu =$ 35 H₁ : $\mu$ < 35,
The following information is known: n = 49, $\bar { x }$ = 37 and $\sigma$ = 16. The standardised test statistic equals: $\begin{array}{|l|l|}\hline \text { A. } & 0.33 . \\\hline \text { B. } & -0.33 \\\hline \text { C. } & -2.33 \\\hline \text { D. } & 2.33 . \\\hline\end{array}$
