Auditors make assessments on the bases of their individual experience, the experience of others, or a combination of experiences. A study of the auditors' methods was performed. The average number of errors is recorded in Table 1.1. At = 0.10, test the claim that errors are equal.

Select the correct answer:

1. None of the answers match my ANOVA.
2. The pvalue of 0.402 is greater than alpha = 0.10 and does not reject H0. It remains plausible that the audit methods are equal.
3. The F test statistic of 0.208 is less than the critical value 2.406 and does not reject H0 at alpha = 0.10. It remains plausible that the audit methods are equal.
4. The pvalue of 0.353 is greater than alpha = 0.10 and does not reject H0. It remains plausible that the audit methods are equal.
5. The pvalue of 0.0998 is less than alpha = 0.10 and rejects H0. The audit methods are not equal.
6. The F test statistic of 5.151 exceeds the critical value 2.406 and rejects H0 at alpha = 0.10. The audit methods are not equal.

Hint:

week # 9 analysis of variance ANOVA,

1-Way ANOVA.

Common errors include:

• Incorrect significance level . = 0.10.
• Not checking the Labels check box when Input Range includes data labels.
• Checking the Labels checkbox when the Input Range does not include data labels.
