A law enforcement agent believes that more than 88% of the drivers stopped on Saturday nights for speeding are under the influence of alcohol. A sample of 60 drivers who were stopped for speeding on a Saturday night were taken and 54 of the drivers in the sample were under the influence of alcohol. Question 1 State the null and alternative hypotheses.  Question 2 Determine the critical value and rejection region (rounded off to three decimals).  Question 3 Calculate the test statistic (rounded off to two decimals) and interpret your finding
