2. Based on a study conducted by the Gallup organization, 80% of Americans believe that the state of moral values in the US is getting worse. Suppose that we obtain a simple random sample of size 80 Americans and determine which of them believes that the state of moral values in the US is getting worse. Do a p hat interval for this sample. p rounded to hundredth n= SE rounded to hundred-thousandth place z' AT 90% confidence level (found on confidence level table in your notes- m (there is a formula for it, round to hundredth place)_ the interval for p-hat (p ± m) small to large
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.
