Question
**Paired Observation Procedures for Company Sample Differences** This exercise involves executing paired observation procedures to determine if the difference between Company A and Company B for the given six samples is positive. **Data Table:** | Sample | 1 | 2 | 3 | 4 | 5 | 6 | |--------|-----|-----|-----|-----|-----|-----| | Company A | 8.8 | 10.0 | 12.5 | 9.7 | 10.0 | 13.2 | | Company B | 8.4 | 10.1 | 12.0 | 9.3 | 9.0 | 13.0 | **Instructions:** - **Hint:** When calculating differences, include both positive and negative signs where applicable. **Hypotheses:** - Null Hypothesis (\(H_0\)): - Alternative Hypothesis (\(H_a\)): \(\mu_d > 0\) **Analysis:** - Sample size (\(n\)): - Degrees of freedom (\(df\)): - Significance level (\(\alpha\)): \(5\%\) - Mean of differences: - **Standard deviation of differences**: \(0.363\) **Decision Criteria:** - Critical value (\(crit\)) = - Test statistic (\(stat\)) = - p-value = These parameters will guide the decision on whether the difference between Company A and Company B is statistically significant.
