A crossover trial is conducted to compare an experimental medication for migraine headaches to a currently available medication. A total of 50 patients are enrolled in the study and a randomized to receive either medication in altering order. The outcome is the resolution of the headache pain in 4 hours. Among the 50 patients, 15 reported resolution of headache pain. Give the following information for a 90% confidence interval. Number of successes = Sample size = Sample proportion (rounded to the two decimal places) = Do you use Z or t? Z or t (value from table) = Standard Error (Rounded to two decimal places)= Margin of Error (Rounded to two decimal places) = Lower limit (Rounded to two decimal places) = Upper limit (Rounded to two decimal places) =
