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 [A]%. Find the standard error for percentage. Hint: The SD for the box model is The standard error for percentage is [B]%. Round your answer to the nearest tenth of a percent(for example 6.3%). The z-statistic is [C]. Round your answer to two decimal places. The p-value is [D]%. Round your answer to the nearest percent(for example 6%) If the significance level is set at 5%, does the pollster have enough evidence to reject the newspaper claim? Write yes or no. [E]
