Question

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

	A	B	C	Total
Male	7	10	19	36
Female	14	2	11	27
Non-binary	5	3	15	23
Total	26	15	45	86

Let ππ represent the percentage of all female students who would receive a grade of C on this test. Use a 90% 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.
