Out of 100 people sampled, 6 had kids. Use the Theory-Based Inference applet to find a 90% confidence interval for the true population proportion of people with kids, π (a) We are 90% confident that the percentage of all people who have kids is between % and % Give your percentage answers rounded to one decimal place. For example, if the applet gives (0.34218, 0.61352) then you would enter 34.2 and 61.4. (b) The sample statistic is . Give your answer as a decimal (NOT a percentage), and do not round. (c) The margin of error is . Give your answer as a decimal using your answers from parts (a) and (b). (d) The confidence interval from part (c) can be written as ±

% and %
Give your percentage answers rounded to one decimal place.
For example, if the applet gives (0.34218, 0.61352)
then you would enter 34.2 and 61.4.
(b) The sample statistic is .
Give your answer as a decimal (NOT a percentage), and do not round.
(c) The margin of error is .
Give your answer as a decimal using your answers from parts (a) and (b).
(d) The confidence interval from part (c) can be written as
±
Give your answers as decimals (NOT percentages), and do not round.
