Answer:
The another term for the 4% value is : Margin of error
Step-by-step explanation:
Dr. Cyril conducts a simple random sample of 500 men.
He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%.
Now, the another term for the 4% value is : Margin of error
Means the estimate of father being unsure about his ability would be between 19% and 27%.
When sample size is increased, the margin of error becomes smaller.
Answer:
it is c
Step-by-step explanation:
Answer:
A circle with center C has chords FB and DA which are equidistant from C.
Step-by-step explanation:
A chord is a straight line drawn from a point on the circumference of a circle to another point on the circumference, without passing through the center of the circle.
From the given question, a circle center C has two chords FB and DA that are equidistant from the center of the circle. The distant of FB from C is CG and the distance of DA from C is CE. But CG = CE, which implies that the two chords have equal distant from the center of the circle.
Therefore line CG from center C intersects FB at G, and line CE from center C intersects DA at E.
Let K = km in 7 weeks
Equation:
K = 7(20)
The answer is 20.4 you just multiply 1.70 by 12
