The number of sneezes were recorded during this time. Further on, the same group of participants were given the opposite treatment with the total sneeze count recorded. Tests for normality for the differences between the drug and placebo were identified. The given P>0.05. Test to see if more sneezes occurred if participants were given the placebo, the given alpha shall be 0.05 Chart is at the bottom.

I.Identify the name of the correct test and why it is the correct choice. Identify the H₀ and H_a. Conduct the test showing all work.

II.Identify the critical value using the given alpha.

III.Conclude based on the results and statistical relevance. Find the 95% confidence interval related to difference in seizures.
