A random sample of Montreal students in 1996 included 210 students who intended to live in Montreal after graduation, and 140 who intended to emigrate. A random sample of Montreal students in 2001 included 252 who intended to live in Montreal after graduation, and 148 who did not. In the five-year period, is the increase in population proportion of those who intended to live in Montreal after graduation statistically significant? Use a 5% significance level. Please write down (1) the value of test statistics, (2) p-value and (3) make conclusion based on p-value.
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.
