Question 4
4.5pts
The test statistic for testing H_0: μ = 100 against H_a: μ ≠ 100 was z = 2.3, with P-value 0.0214. Which of the following is the appropriate conclusion? Assume α = 0.05.
O Since the P-value is less than 0.05, we conclude that μ = 100.
O Since the P-value is less than 0.05, we are unable to conclude that μ ≠ 100.
O Since the P-value is less than 0.05, we need to know the sample size.
O Since the P-value is less than 0.05, we conclude that μ ≠ 100.
Corrections made:
- Corrected the subscript notation for the null and alternative hypotheses (H_0 and H_a).
- Corrected the Greek letter μ (mu) for the population mean.
- Corrected the inequality symbol in the alternative hypothesis (≠ instead of !=).
- Corrected the alpha symbol (α) for the significance level.
- Removed unnecessary spaces and corrected the formatting of the options.
