## Are the Snow Conditions a Factor in the Number of Visitors at a Ski Resort?### Data CollectionThe table below presents data on the number of visitors under three different snow conditions:| Hard Packed | Machine Made | Powder ||-------------|--------------|--------|| 1837 | 1757 | 1614 || 1838 | 1032 | 1975 || 2052 | 1558 | 2790 || 1608 | 1466 | 1889 || 2405 | 1933 | 1915 || 1862 | 1507 | 1922 || 2199 | 1124 | 1708 || 1475 | 1583 | 2787 || 1350 | | 2776 |### AnalysisAssumptions:- Distributions are normal.- Populations have equal standard deviations.- Data collected independently and randomly.- Level of significance ($\alpha$) = 0.01.### Hypotheses- **Null Hypothesis ($H_0$)**: $\mu_1 = \mu_2 = \mu_3$- **Alternative Hypothesis ($H_1$)**: At least two of the means differ from each other.### Statistical Testing1. **Select a Test**: Choose the appropriate statistical test. 2. **Calculate Test-Statistic**: Fill in the test-statistic value to 3 decimal places. 3. **Determine P-value**: Provide the p-value to 4 decimal places.4. **P-value Comparison**: Decide if the p-value is less than or greater than $\alpha$.5. **Drawing Conclusions**: Select an appropriate hypothesis based on the p-value comparison.### Conclusion6. **Final Decision**: - **Option 1**: There is insufficient evidence to support the claim that snow conditions are a factor in the number of visitors at a ski resort. - **Option 2**: There is sufficient evidence to support the claim that snow conditions are a factor in the number of visitors at a ski resort.Complete the analysis to reach a conclusion on whether snow conditions significantly influence visitor numbers.
