Question
![**Hypothesis Test**
It is conjectured that the proportion of all people who went trick-or-treating and also had a pumpkin carved into a jack-o'-lantern at their home is 0.62. Of interest is to test this claim versus the alternative that the proportion of all people who went trick-or-treating and also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62.
A simple random sample of 270 people who went trick-or-treating is selected, and 162 of them also had a pumpkin carved into a jack-o'-lantern at their home (and the other 108 did not). If appropriate, use this information to test if the proportion of all people who went trick-or-treating and also had a pumpkin carved into a jack-o'-lantern at their home is less than 0.62 at the α = .10 level of significance.
**Which of the following provides both the correct null and the correct alternative hypothesis for this situation?**
- [ ] H0: π = 0.62; Ha: π < 0.62
- [ ] H0: π = 0.71; Ha: π < 0.71
