he resulting z-score will be positive and the sampling distribution is approximately Normal. resulting z-score wil be negative and the sampling distribution is approximately Normal. 1.53 is less than the population proportion of 0.57 and because the sampling distribution is approximately Non is less than the population proportion of 0.57 and because the sampling distribution is approximately Normal are overweight or obese.
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.

![A recent study reported that 57% of the children in a particular community were overweight or obese. Suppose a random sample of 500 public school children is taken from this community. Assume the sample was taken in such a way that the conditions for using the Central Limit Theorem are met. We are interested in finding
the probability that the proportion of overweight/obese children in the sample will be greater than 0.53. Complete parts (a) and (b) below.
a. Before doing any calculations, determine whether this probability is greater than 50% or less than 50%. Why?
A. The answer should be greater than 50%, because the resulting z-score will be positive and the sampling distribution is approximately Normal.
O B. The answer should be less than 50%, because the resulting z-score will be negative and the sampling distribution is approximately Normal.
C. The answer should be greater than 50%, because 0.53 is less than the population proportion of 0.57 and because the sampling distribution is approximately Normal.
O D. The answer should be less than 50%, because 0.53 is less than the population proportion of 0.57 and because the sampling distribution is approximately Normal.
b. Calculate the probability that 53% or more of the sample are overweight or obese.
P(p20.53) = (Round to three decimal places as needed.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc2f49e8b-eabf-4587-a1db-d4952a79435d%2Ffd7eb76c-877e-444c-a7cd-9090c0ac2a60%2Frw370hu_processed.png&w=3840&q=75)
