Question

Political parties want to know what groups of people support them. The General Social Survey (GSS) asked its 2012 sample, "Generally speaking, do you usually think of yourself as a Republican, Democrat, Independent, or what?" The GSS is essentially an SRS of American adults. Here is a large two-way table breaking down the responses by the highest degree the subject held:

	NONE	HIGH SCHOOL	JR. COLLEGE	BACHELOR	GRADUATE
Strong Democrat	51	159	34	56	52
Not strong Democrat	46	175	28	64	39
Independent, near Democrat	35	119	14	42	28
Independent	103	188	23	38	28
Independent, near Republican	24	76	19	27	14
Not strong Republican	13	126	18	64	26
Strong Republican	11	100	22	41	18
Other party	8	22	1	17	8

Give a 95% confidence interval (±±0.0001) for the proportion of adults who are "Independent."
