Call me: A sociologist wants to construct a 95% confidence interval for the proportion of children aged 8-10 living in New York who own a smartphone. Part: 0 / 3 Part 1 of 3 (a) A survey by the National Consumers League estimated the nationwide proportion to be 0.29. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.02? A sample of children aged 8-10 living in New York is needed to obtain a 95% confidence interval with a margin of error of 0.02 using the estimate 0.29 for p. X
