Question

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

	A	B	C	Total
Male	8	14	16	38
Female	12	7	17	36
Total	20	21	33	74

Let pp represent the percentage of all male students who would receive a grade of C on this test. Use a 98% confidence interval to estimate p to three decimal places.

Enter your answer as a tri-linear inequality using decimals (not percents).

< 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.
