Researchers are interested in the effect of a high-protein diet on the performance of undergraduates on the Verbal GRE. They start with no expectations as to whether students on the high-protein diet will perform better than students in a control group who follow their usual diet. After noticing that students on the high-protein diet tended to have higher GRE scores, the researchers decided to test a one-sided alternative about the mean Verbal GRE scores, Họ : Hhigh-protein diet = Hcontrol diet Ha : Hhigh-protein diet > Hcontrol diet The researchers find z = 2.24 with one-sided P-value is P = 0.0125.

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 p…

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.
