Consider the following hypothesis and mean comparison results table.
Ha: In a comparison of tourist attractions, national parks have more visitors, on average, than national
monuments.
Mean visitors at national parks and monuments

1. What is the null hypothesis (H0)?
2. What is the dependent variable?
3. What is the independent variable?
4. What is the unit of analysis?
5. Based on the values in the mean comparison table, do you have support for the hypothesis? In
other words, is the relationship in the hypothesized direction?
6. The t-statistic value is 2.81. Is the relationship statistically significant at the p < .05 level?
Explain how you know. [Hint: you will need to calculate the degrees of freedom (df) and find
the critical value to compare to the t-statistic value.]
7. Do you have support for the hypothesis? Can you reject the null hypothesis? Explain how you
know
