A political campaign is interested in whether a geographic difference existed in support for raising the minimum wage in a certain state. Polls were conducted in the two largest cities in the state about raising the minimum wage. In city 1, a poll of 800 randomly selected voters found that 432 supported raising the minimum wage. In city 2, a poll of 1000 randomly selected voters found that 475 supported raising the minimum wage. What type of hypothesis test should be performed? Select Select Pi = Ex: 0.123 P2 = = Ex: 0.123 = Ex: 0.123 Two-tailed z-test Test statistic = Ex: 0.12 Right-tailed t-test p-value = Ex: 0.123 Left-tailed z-test Does sufficient evidence exist to support the claim th between the two cities at the a = 0.1 significance differs Right-tailed z-test
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.
