Ggoogle recently commissioned a poll about computer science teaching in schools. they found that three-quarters of schools teaching grades 7-12 do not have computer science classes that teach coding. their margin of error for estimating the proportion of schools that teach coding was 0.03. what does that margin of error represent? the prediction is that the sample proportion (0.75) falls within 0.03 of the population proportion of schools teaching coding. the prediction is that the sample proportion (0.75) falls outside 0.03 of the population proportion of schools teaching coding. the prediction is that if many confidence intervals were created, 97% of them would contain the population proportion. the prediction is that 3% of confidence intervals calculated in a similar way won't contain the population proportion. the prediction is that 97% of schools teach coding.
