A park manager wants to determine if the amount of support for the national park is different among community members. More specifically, he/she wants to know if there is a difference between males and females.
1. What could be the potential research question for this problem?
2. What could be the hypothesis and alternative hypothesis for this problem?
3. Looking at the end-results of the T-Test that are here below, especially the MEAN of females and males, does it REJECT or FAIL TO REJECT the null hypothesis?Why?( null hypothesis= there was no statistical difference between the amount of support for the national park between male and female community members)

Solution:
1. What could be the potential research question for this problem?
Answer: The potential research question for this problem is whether there is a significant difference between the average amount of support for the national park among males and females.
2. What could be the hypothesis and alternative hypothesis for this problem?
Answer: The null and alternative hypothesis for this problem is:
3. Looking at the end-results of the T-Test that are here below, especially the MEAN of females and males, does it REJECT or FAIL TO REJECT the null hypothesis? Why?
Answer: We fail to reject the null hypothesis because the p-value is 0.229 which is greater than the significance level 0.05. We therefore conclude that there is there was no statistical difference between the amount of support for the national park between male and female community members
