Question

Giving a test to a group of students, the grades and gender are summarized below

	A	B	C	Total
Male	15	16	20	51
Female	17	18	8	43
Total	32	34	28	94

Let p represent the population proportion of all female students who received a grade of C on this test. Use a 90% confidence interval to estimate p to four decimal places if possible.
< p <

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
