**Survey Analysis on Online Education Perception Among College Presidents**A recent survey found that 55% of college presidents believe that their online education courses are as good as or superior to traditional face-to-face instruction. The following prompts illustrate the steps to test the claim made by the survey statistically.### Question:**a. Give the null hypothesis for testing the claim made by the survey.** **b. Give the rejection region for a two-tailed test conducted at α = 0.01.**#### Answer:**a. What is the null hypothesis?**The null hypothesis (H₀) for the survey claim can be expressed as:\[ H₀: p = 0.55 \]where \( p \) represents the proportion of college presidents who believe that their online courses are as good as or superior to traditional face-to-face instruction.**b. What is the rejection region?**The rejection region for a two-tailed test at α = 0.01 requires determining the critical z-values that correspond to this significance level. The options given are:- **A. \[ \_\_\_\ < z < \_\_\_\ ]**- **B. \[ z < \_\_\ \text{ or } z > \_\_\ ]**- **C. \[ z < \_\_\_\ ]**- **D. \[ z > \_\_\_\ ]**To find the critical z-values, we need to locate the z-scores that form the cutoff points for the tails. The area in each tail will be \(\frac{\alpha}{2} = 0.005\). Using z-tables or a statistical calculator, the critical values for a two-tailed test at α = 0.01 are approximately ±2.576.Thus, the rejection region to test this hypothesis is:\[ z < -2.576 \text{ or } z > 2.576 \]Figuratively, this corresponds to option:- **B. \[ z < -2.576 \text{ or } z > 2.576 \]**

Here we want to know null hypothesis and rejection region.

A researcher is interested in assessing if there are differences in the average number of monthly religious event attendances across religious affiliations. Religious event attendance is measured as an interval-ratio variable: it is the number of events that each survey respondent reported attending in the previous month. Religious affiliation is measured as a nominal variable with the following categories: Protestant, Catholic, Jewish, Muslim, Hindu, Buddhist, other, and not religious. Which of the following hypothesis tests would be appropriate, given the types of variables presented? O Chi-square test O Two-sample difference-of-proportions z-test O ANOVA O One-sample difference-of-proportions z-test
