K A double-blind study using random assignment was done of pregnant women in a certain country. Women were given fish oil or a placebo during pregnancy. Their children were followed during the first 5 years of life to see if they developed asthma. The results are summarized in the accompanying table. Complete parts (a) through (c) below. Developed asthma Yes No Fish Oil 70 Placebo 99 741 718 The Random and Independent condition The Large Samples condition The Big Populations condition The Independent Samples condition reasonably be assumed to hold. c. Find the 95% confidence interval for the difference in the proportion of children who develop asthma in the two groups. Based on your confidence interval, can we conclude that there is a difference in the population proportions? The 95% confidence interval for the difference (treatment minus placebo) is (.). (Round to three decimal places as needed.) that the difference in is between the lower and upper boundaries of the confidence interval. The interval 0, suggesting that it plausible that the proportions are the same. Since the boundary values during pregnancy developed asthma. we proportion of children whose mothers took fish oil A double-blind study using random assignment was done of pregnant women in a certain country. Women were given fish oil or a placebo during pregnancy. Their children were followed during the first 5 years of life to see if they developed asthma. The results are summarized in the accompanying table. Complete parts (a) through (c) below. Developed asthma Yes No Fish Oil 70 741 Placebo 99 718 a. Calculate and compare the percentages of children who de eloped asthma in the fish oil group and in the placebo group. The percentage that developed asthma in the treatment group, ☐ %, is the percentage that developed asthma in the placebo group, ☐ %, so children whose mother's the fish oil during pregnancy did better. The difference in percentages (treatment minus placebo) is ☐ %. (Round to one decimal place as needed.) b. Check that the conditions for using a two-population confidence interval hold. The Random and Independent condition The Large Samples condition The Big Populations condition The Independent Samples condition reasonably be assumed to hold. c. Find the 95% confidence interval for the difference in the proportion of children who develop asthma in the two groups. Based on your confidence interval, can we conclude that there is a difference in the population proportions?
