Question$\begin{array}{l}H_{0}: \mu=7, \quad S=4.4, \bar{X}=9, n=60 \\ H_{a}: \mu \neq 7\end{array}$

Studdy Solution
Since the calculated t-statistic exceeds the critical value, or the p-value is less than the significance level, we reject the null hypothesis.
Conclusion: There is sufficient evidence to suggest that the population mean $\mu$ is not equal to 7.
