An accounting firm is interested in estimating the error rate in an ongoing compliance audit. The population consists of 828 claims, and the firm audits a total of 85 claims. In each of the 85 claims, a total of 215 items were reviewed to determine errors. From the audit, it was found that 1 claim had 4 out of 215 items that have errors, next, one claim had 3 errors, 4 claims had 2 errors, 22 claims had 1 error and the remaining 57 claims had no errors. Assume the claim is the primary sampling unit (cluster) and the item is the second sampling unit, get a) Total errors for 85 claims and standard errors
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.
