A Researcher Believes That the Median Low Temperature for February $\begin{array} { l l l l l l l l l l l l l l l l } - 7 & - 7 & - 3 & 2 & 3 & 10 & 14 & 16 \end{array}$

question 3

Multiple Choice

A researcher believes that the median low temperature for February is 8 degrees. A random sample of 14 years yields the following data: $\begin{array} { l l l l l l l l l l l l l l l l } - 7 & - 7 & - 3 & 2 & 3 & 10 & 14 & 16 \end{array}$
At $= .05$ , should the researcher's hypothesis be accepted or rejected?
You may use the following abbreviated table of critical values (two-tailed, =.05) taken from Table J:
$\begin{array}{|l|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}\hline & 11 & 12 & 13 & 14 & 15 & 16 & 17 & 18 & 19 & 20 & 21 & 22 & 23 & 24 & 25 \\\hline \text { critical value } & 1 & 2 & 2 & 3 & 3 & 3 & 4 & 4 & 4 & 5 & 5 & 5 & 6 & 6 & 6 \\\hline\end{array}$

• A) Reject because the test value 4 is more than the critical value 3
• B) Do not reject because the test value 3 is equal to the critical value 3
• C) Reject because the test value 4 is more than the critical value 2
• D) Do not reject because the test value 3 is more than the critical value 2
