Numerical and Verbal Hypothesis Statement
In business, small and large or personal the ability to have information to make a decision is essential. “Hypothesis testing is used in both science and business to test assumptions and theories and ultimately guide managers when faced making decisions.” (Doane & Seward, 2007, page 347, Chapter 9). We reviewed and analyzed the data set, Real Estate and developed a hypothesis test. The hypothesis test can be described with the following steps:

Step 1: State the Hypothesis
Does the housing in San Diego cost more than the national average? For this example, we have estimated that average housing cost in San Diego to be $300,000. According to the data set, the national average is $221,103. The null hypothesis is San Diego housing is more than or equal to the national average using a confidence level of 95%. The alternative hypothesis is that San Diego housing is not more than the national average. These two hypotheses are expressed numerically as follows: H0: µ ≥ $ 221.1029

H1: µ < $ 221.1029

Step 2: Specify the Decision Rule
The decision rule is reject the null hypothesis if z > 1.96 or if the p-value is less than alpha. Alpha is this is equal to 0.05. Reject H0 if z > + 1.645
Reject H0 if p < α
Step 3: Calculate the Test statistics:

The above chart represents the national average as proved by the Real Estate data set. The data has been sorted from lowest to highest and divided by six to form the various groups. The descriptive statistics is shown in the table below.

Using the numbers from the table, the z value for San Diego is calculated as follows: x̄ = 300,000 z = x̄- μ/s√n,
μ = 221.1029 z =...

Statistical Inference
Testing of Hypothesis
Type I Error:
Rejection of the null hypothesis when it is true is called a type I error.
Type II Error:
Acceptance of the null hypothesis when it is false is called a type II error.

...Simple Hypothesis: A statistical hypothesis which specifies the population completely (i.e. the form of probability distribution and all parameters are known) is called a simple hypothesis.
1. Composite Hypothesis: A statistical hypothesis which does not specify the population completely (i.e. either the form of probability distribution or some parameters remain unknown) is called a Composite Hypothesis....

SUPPORING DATA:
The hypothesis of our issue is the average graduation rate of students studying in New York public schools. The claim is that the graduation rate is more than 50.
So,
Mu= average graduation rate of students in New York Public Colleges
H-zero (Null Hypothesis): Mu = 50
H- Alt: Mu > 50

“A dream doesn't become reality through magic; it takes sweat, determination and hard work”.
Quotes the famous General Colin Powell, giving hope and a new dimension to people in distress to look up to fulfill their dreams despite the many roadblocks in front of them. One cannot pursue his dream in just a blink of an eye, it needs determination and hard work to achieve our dreams.
I have also taken inspiration from these brave words and feel one can...

...Case No 7
Tiresome Tire I
Introduction:
This case is about Hypothesis Testing, there is a tire manufacturing company which is producing tire with the strength 2800 pound per square inch (psi), we have to test Null Hypothesis i.e. H0 : u> 2,800 psi, where u is the mean strength of large batch of tire and population SD is 10 psi.
Calculation:
We have to test Null Hypothesis based on given information.
Type I error will result in the...
