In a sample of 50 cases of juice, 3 had defects. The sampling method had a margin of error of 0.04.
What is the interval estimate for the proportion that would have defects in the form
(lower limit, upper limit)?
0
(0.6, 0.14)
O (0.1,0.9)
0 (0.02,0.10)
0
(0.4,0.12)

the margin of error is on either side of that

(0.02, 0.10)

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
