Question
**Finding Critical Values: An Exercise** This exercise provides a scenario to find the critical values of \( t_{\text{crit}} \). The problem assumes normality and is based on the following hypotheses: - Null Hypothesis (\( H_0 \)): \(\mu = 50\) - Alternative Hypothesis (\( H_a \)): \(\mu \neq 50\) Parameters given for calculation are: - Sample size (\( n \)): 25 - Significance level (\( \alpha \)): 0.05 **Select the correct critical value:** - a. \( \pm 2.064 \) - b. \( \pm 1.711 \) - c. \( \pm 1.708 \) - d. \( \pm 2.060 \) This exercise tests the student's understanding of critical values in hypothesis testing and their ability to apply statistical concepts accurately.
