A random sample of size 20 drawn from a normal population yielded the following results: $\bar{x}=49.2, s=1.33$.
In testing: $H_{0}: \mu=50$ versus $H_{1}: \mu \neq 50$ at a 0.01 level of significance, the decision is to: not reject the null hypothesis. reject the null hypothesis.

Studdy Solution
Compare the calculated test statistic to the critical values:
Since $-2.69$ is greater than $-2.861$ and less than $2.861$, it falls within the range of not rejecting the null hypothesis.
Decision: Not reject the null hypothesis.
The decision is to:
$$\text{Not reject the null hypothesis.}$$
