Show all steps/calculator commands using a ti84 graphing calculator. 1. Conduct a hypothesis test showing all of your steps. From a random sample of 89 customers using a certain bank, 13 said they were not happy with the services they received. That bank reports that less than 20% of its customers are unsatisfied with its services. Test this claim with an 8% level of significance. 1. State the hypotheses and label the claim. Is the test left-tailed, right-tailed, or two-tailed? 2. What is/are the critical value(s)? Draw a picture. 3.What is the P-value AND test-statistic? 4. State the conclusion. Give two reasons for your decision to reject/not reject H0 base
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.

1. Conduct a hypothesis test showing all of your steps.
From a random sample of 89 customers using a certain bank, 13 said they were not happy with the services
they received. That bank reports that less than 20% of its customers are unsatisfied with its services. Test
this claim with an 8% level of significance.
1. State the hypotheses and label the claim. Is the test left-tailed, right-tailed, or two-tailed?
2. What is/are the critical value(s)? Draw a picture.
3.What is the P-value AND test-statistic?
4. State the conclusion. Give two reasons for your decision to reject/not reject H0 based on:
5. Test statistic compared to critical value P-value compared to α
Then, relate back to the original claim.
