**Hypothesis Testing Example**When asked whether marriage is becoming obsolete, 720 out of 2058 randomly selected adults responded "yes" in a survey. We are testing the hypothesis that the population proportion that believes marriage is becoming obsolete is more than 33%, using a significance level of 0.05. One of the following figures is correct. Indicate which graph matches the alternative hypothesis, \( p > 0.33 \). Report and interpret the correct p-value.---**Choose the correct graph below.**- **Option A:** - **Graph:** Bell-shaped normal distribution curve, right-tailed test - **z = 1.9155** - **p = 0.0277** (shaded area on the right tail)- **Option B:** - **Graph:** Bell-shaped normal distribution curve, two-tailed test - **z = 1.9155** - **p = 0.9723** (both tails shaded)- **Option C:** - **Graph:** Bell-shaped normal distribution curve, right-tailed test - **z = 1.9155** - **p = 0.0554** (shaded area on the right tail)---**Conclusion:**Because the p-value is **less than** the significance level, **reject** the null hypothesis. There **is** sufficient evidence to conclude that the population proportion **is greater than** 0.33.

The hypotheses for the test are given below: Null hypothesis: H0: p ≤ 0.33 Alternative hypothesis:…
