A domestic manufacturer of watches purchases quartz crystals from a Swiss firm. The crystals are shipped in lots of 1,000. The acceptance sampling procedure uses 20 randomly selected crystals. a. Construct operating characteristic curves for acceptance numbers of 1, 2, and 3 (to 4 decimals). p= 0.03 p= 0.07 p = 0.1 p= 0.12 p= 0.17 1 2 3 b. If po is 0.03 and pi = 0.1, what are the producer's and consumer's risks for each sampling plan in part (a) (to 4 decimals)? At po = 0.03 Producer's Risk At pi = 0.1 Consumer's Risk 1 00
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.
