State H1. 3. State the value of α. 4. State the value of the test statistic. 5. State the p-value. 6. State the decision in terms of H0 and why.7. State the decision in terms of the problem.b.If appropriate, use the Marascuilo procedure and α = .01 to determine which, if any, year groups are significantly different in the proportion of passengers who book tickets online. c.Would the results change if samples of size 300 were used?
