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 V0.6*0.4 =0.49 The standard error for percentage is %. Round your answer to the nearest tenth of a percent(for example 6.3%). The z-statistic is Round your answer to two decimal places. The p-value is %. 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.
