The Gallup organization has been tracking religious attitudes and practices in the United States since 1937, when they reported that 73% of the US claimed membership in a church. That number went down to 69% in 2000 and down again to 62% in 2010. A recent report stated that only half of US adults now consider themselves members of a church. The report was based on a study of 6,000 randomly selected US adults which resulted in 2,940 who said that they belonged to a church. Is the proportion of US adults who belong to a church different than 50%? Use alpha=0.05. STATE: What is a 90% confidence interval estimate for the proportion of all of US adults who belong to a church? PLAN: State the name of the appropriate estimation procedure (e.g. one-sample t confidence interval for estimating the mean difference). (1 pt) Note: You have already described the parameter being estimated in Part A, so you don't have to repeat it here..
