a poll from the San Diego Union Tribune found that 53.5% of drivers stated that they always make a complete stop at stop signs. one of the groups from previous semester did an observational study to determine factors and might indicate which drivers will come to a complete stop at a four way stop. they calculated a 90% confidence interval for the true proportion of San Diego drivers who came to a complete stop to be (0.4378, 0.6022). Based on this interval, is there enough evidence to indicate that the value from the union tribune poll was incorrect? explain your answer. please help me
