In testing the hypotheses: $H _ { 0 } : \mu =$ 35 H₁ : $\mu$

Question

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}
