An experiment is any study that seeks to answer a research question. In a double blind study neither the researcher, nor the experimental subjects know which individuals receive the treatment and which do not. e) The coefficient of determination gives the proportion of the change in the f) response variable the can be attributed to the change in the explanatory variable and the regression s line.
Family of Curves
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 families appear commonly in the solution of differential equations. When a constant of integration is added, it is normally modified algebraically until it no longer replicates a plain linear transformation. The order of a differential equation depends on how many uncertain variables appear in the corresponding curve. The order of the differential equation acquired is two if two unknown variables exist in an equation belonging to this family.
XZ Plane
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 real numbers and a is the horizontal coordinate and b is the vertical coordinate. This type of plane is called two-dimensional and it contains two perpendicular axes, the horizontal axis, and the vertical axis.
Euclidean Geometry
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) geometry was introduced by the Greek mathematician Euclid, and that is why it is called Euclidean geometry. Euclid explained this in his book named 'elements'. Euclid's method in Euclidean geometry involves handling a small group of innately captivate axioms and incorporating many of these other propositions. The elements written by Euclid are the fundamentals for the study of geometry from a modern mathematical perspective. Elements comprise Euclidean theories, postulates, axioms, construction, and mathematical proofs of propositions.
Lines and Angles
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.
![8) Some claim that magnets can be used to reduce pain. Design a double-blind experiment to
test this claim. Write a brief proposal that includes important details including the number
of subjects, how subjects are assigned to groups, and how you will make the study double
blind.

A census gets information from every member of the population.
A sample gets information from a proper subset of the population.
A stratified sample is where you partition the population into two or more groups

As the sample size (n) increases, the standard deviation of x from that
sample decreases, this assumes the standard deviation is positive.. siugoy
j)
In the p-value approach, if p-value>a (the level of significance) we reject
the null hypothesis.
k)
If you fail to reject the null hypothesis at the 5% level, then the probability
that you are wrong is always 5%.
The level of significance is the probability of rejecting the null hypothesis
when the null hypothesis is true.
