Questions 13-16 are related to the following To build a 95% interval estimate for the proportion of Indiana adult population who are obese, a random sample of Hoosier adults is selected. The sample is shown in worksheet DATA13. 13 The point estimate of the population proportion is, 0.461 0.452 0.443 0.434 a b d 14 a b с d 15 a b d 16 b d The standard error of the sample proportion is, 0.0219 0.0207 0.0195 0.0184 The interval estimate with a 95% confidence level is, 0.436 0.430 0.423 0.413 0.468 0.473 0.480 0.490 Suppose you want to build an interval estimate for the proportion of Indiana adults who are obese with a 95% confidence level and a margin of error of ±0.03 (3 percentage points). What is the minimum sample size to achieve this margin of error? Use the point estimate from question 13 for planning value. 1058 1017 978 940
