15. A March 2012 Gallup poll asked American adults whether they thought the news media exaggerate the seriousness of global warming. The proportion who responded "No" was 0.63. Is this good evidence that the majority of American adults do not believe the news media exaggerate the seriousness of global warming? The answer depends on the size of the sample. Let p denote the true proportion of American adults who do not believe the news media exaggerate the seriousness of global warming. Give a 95% confidence interval for the true proportion p for three different sample sizes. Use p = 0.63 in all three tests. But use three different sample sizes, n = 25, n = 100 and n = 400. n SE (+0.0001) 95% confidence interval (10.0001) 25 to 100 to 400 to cBook Check Syntax
