Suppose that for a certain lness, the probabiity is 45% that a given patient will improve without treatment. Then the probabiity that at leastn out of 20 patients will improve without treatment is given in the following table 10 11 12 13 14 15 16 Probability at least n improve 0.41 0.25 0.13 0.058 0.021 0.0064 0.0015 Suppose we count the test significant if the p-value is 0.30 or less. HHow many patients must show improvement in order to make the test statistically significant? patients etlouk
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.
