Based on Sample Data, the 95% Confidence Interval Limits for the Population

question 41

Short Answer

Based on sample data, the 95% confidence interval limits for the population mean are LCL = 124.6 and UCL = 148.2. If the 5% level of significance were used in testing the hypotheses:
H₀ : $\mu$ = 150
H₁ : $\mu$ $\neq$ 150,
The null hypothesis: $\begin{array}{|l|l|}\hline A&\text { would not be rejected.}\\\hline B&\text {would be rejected. }\\\hline C&\text { would have to be revised.}\\\hline D&\text {There is insufficient information to decide whether to maintain or reject the }\\&\text {null hypothesis. }\\\hline\end{array}$

Null Hypothesis

The default hypothesis in statistical testing that assumes no effect or difference, stating that any observed variability is due to chance.

Directional

Pertains to hypothesis testing or research questions that specify the direction of the expected relationship or difference between variables.
