Sample size: n = 900 adults nationwide. Margin of error 3.3.

72% of persons feel vaccinations should be required.

Level of significance .02

Test statistic of 2.13

The null hypothesis is that 72% of people want to have vaccinations required.

95% confidence level

Given that .02 is the significance level, the critical z scores are -2.33 and 2.33, with a test statistic of 2.13, I will fail to reject the null hypothesis.

B: Determine a level of significance that would have the opposite result of .02.Explain why this level of significance would have the opposite result.
