A “water diet" requires you to drink one cup of water every hour from the time you get up until you go to bed, but otherwise allows you to eat whatever you like. Four adult volunteers agree to follow the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are: Subject Weight before diet Weight after diet A B D 180 125 240 150 170 130 215 152 Which of the following is the correct standardized test statistic for a test of the null hypothesis that the water diet has no effect on weight loss? 7-0 13.638 7-0 t = 13.638 173.75 –166.75 46.56 36.09² 4 4 173.75 –166.75 46.56 , 36.092 4 4 173.75 –166.75 46.562 36.09?

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
