A newspaper believes that the approval rating of the current mayor is 60%. A pollster believes that it is less than 60% and sets out to prove it. A simple random sample of 900 people are surveyed and 504 responded that they approved of his work. The null hypothesis is that the mayor's approval rating is 60%. The observed percentage is %. Find the standard error for percentage. Hint: The SD for the box model is √0.6*0.4=0.49 The standard error for percentage is %. Round your answer to the nearest tenth of a percent(for example 6.3%).
