The hypothesis are given as follows:
Null hypothesis: [tex]H_0: \pi_1 = \pi_2[/tex]Alternative hypothesis: [tex]H_1: \pi_1 \neq \pi_2[/tex]The test statistic is given as follows:
z = 38.92.
The critical value is given as follows:
z = 1.96.
The conclusion is given as follows:
Since the test statistic is greater than the critical value, reject the null hypothesis. There is sufficient evidence to conclude that there is a significant difference between the proportion of Superbanked and the Unbanked with respect to using credit cards.
The p-value is of: 0.
The p-value is the probability that in a random sample of 1,000 Superbanked consumers and 1,000 Unbanked customers, the difference between the proportions of Superbanked and Unbanked customers is at least 0.65.
What are the hypothesis tested?At the null hypothesis, it is tested if the hypothesis are equal, that is:
[tex]H_0: \pi_1 = \pi_2[/tex]
At the alternative hypothesis, it is tested if they are different, that is:
[tex]H_1: \pi_1 \neq \pi_2[/tex]
We are testing if the two proportions are different, hence we have a two-tailed test, using the z-distribution, with a significance level of 0.05, and the critical value is given as follows:
z = 1.96.
Then the decision rule is given as follows:
|z| < 1.96: do not reject the null hypothesis.|z| > 1.96: reject the null hypothesis.How to obtain the test statistic and p-value?To obtain the test statistic, we need to obtain the proportion and the standard error for each sample, as follows:
[tex]\pi_1 = 0.89, s_1 = \sqrt{\frac{0.89(0.11)}{1000}} = 0.0099[/tex][tex]\pi_2 = 0.24, s_1 = \sqrt{\frac{0.24(0.76)}{1000}} = 0.0135[/tex]Hence, for the distribution of differences, the mean and the standard error are given as follows:
p = 0.89 - 0.24 = 0.65.s = square root (0.0099² + 0.0135²) = 0.0167.The test statistic is given by the division of the mean by the standard error, hence:
z = p/s = 0.65/0.0167 = 38.92.
Using a z-distribution calculator, with a two-tailed test and z = 38.92, the p-value is of 0.

Nayeli is proofreading a 757575 page manuscript. Filémon is line editing a 404040 page manuscript.
Since proofreading is faster, Nayeli completes 111111 pages an hour, but Filémon only completes 444 pages an hour.
When Nayeli and Filémon have the same number of pages left, how many pages will that be?
Solve the linear equations we get the required pages left are 20 pages after 5 hours.
What is a system of equations ?A system of linear equations consists of two or more equations, and one attempts to solve the equations together. Each equation in a set of linear equations has a corresponding straight line, and the intersection of the two lines is the place that has to be found.A group of equations comprising one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations cross, are the solutions of systems of equations.Given :
Nayeli is proofreading a 75-page manuscript. Filémon is line editing a 40-page manuscript. Since proofreading is faster, Nayeli completes 11 pages an hour, but Filémon only completes 4 pages an hour. When Nayeli and Filémon have the same number of pages left, how many pages will that be is to be determined.
Let the time be x,
75 - 11x = 40 - 4x
35 = 7x
x = 5
Now,
Number of pages = 40 - 4x = 40 - 20 = 20
Thus, the required pages left are 20 pages after 5 hours.

The null and alternative hypothesis when the average weight of dogs is 15.6 pounds will be;
Null hypothesis; H0: μ = 15.6 pounds
Alternative hypothesis; Ha: μ ≠ 15.6 pounds
What is the difference between null and alternative hypotheses?In statistical hypothesis testing, null and alternative hypotheses are used. A test's null hypothesis always predicts that there will be no effect or relationship between variables, whereas the alternative hypothesis states your research prediction of an effect or relationship.
The null hypothesis assumes that any difference between the selected characteristics in a set of data is due to chance. For example, if the expected earnings for the gambling game are truly zero, then any difference between the data's average earnings and zero is due to chance.
In conclusion, a null hypothesis is what, the researcher tries to disprove whereas an alternative hypothesis is what the researcher wants to prove.

Compare and contrast mediation with arbitration.
It is important to note that in a mediation process, a neutral, qualified mediator attempts to assist disputants in reaching an agreement on their own. An impartial, trained arbitrator serves as a judge in arbitration and is responsible for settling the issue.
What is Mediation and what is Arbitration?By definition, Mediation is a procedure in which a neutral third person, known as a mediator, assists opposing parties in reaching an amicable settlement to their disagreement.
The mediator does not have the jurisdiction to make a decision or force a settlement on the parties; rather, the mediator promotes discussion and negotiation between the parties in order for them to achieve a mutually agreeable agreement.
On the other hand, Arbitration, is defined as a formal, legally binding procedure in which an arbitrator, an impartial third party, makes a judgment to resolve the disagreement. The parties agree to submit their disagreement to the arbitrator, who hears evidence and arguments from both sides and then renders a binding judgment known as an arbitration award.
Thus, it is important to note the difference and when to use which.

What is graph?Mathematical structures known as graphs are used to model pairwise relationships between objects. Graph theory is the study of these mathematical structures. Vertices (also known as nodes or points) and edges are what make up a graph in this context (also called links or lines).
It is possible to distinguish between directed and undirected graphs, where edges connect two vertices asymmetrically and symmetrically, respectively. One of the primary topics in discrete mathematics is graphs.
The variation of one variable in comparison to that of one or more other variables is represented by a graph, which is a diagram (such as a collection of one or more points, lines, line segments, curves, or areas).
