Hypothesis validation is really a methodical use of statistics to establish the probability of claims or ideas that are true or not. We select sample data to study about its behavior in a set of given population data is called hypothesis testing. Further, we establish the criteria for hypothesis decision by setting 5% level of significance to reject or accept the null hypothesis. The criteria are "low barometric pressure and temperature causing breathing problems" meaning the probability of having a sample mean with in the bell curve that is beyond 1.96 standard deviation from the population mean is less than a 5%. We also determine probability 'p ', which is obtaining a sample mean as claimed value in the null hypothesis testing. We

As we can see from the scattered plot, there are patterns of all the 3 parameters happened in only very few instances and this correlation has no unsuspected correlations. It does not look like there is a strong correlation. An intelligent correlation analysis can lead to a greater understanding of data, but we do not have much correlation. Null Hypothesis

In this paper, we validate the hypothesis with the help of data gathered and the statistical calculation to support or invalidate the premise statement. The stated null hypothesis is that humans cannot hold the breath not more than 25 seconds counted in severe weather condition, and the alternate hypothesis is that they can hold the breath more than 25 seconds count. The mean is what we collected for three people over 20 days and referred as a sample mean. For our hypothesis test, we will use 5% significance level. Our source data confirm standard normal distribution, so we calculate z score and find out how much standard error deviated from the mean. We use z-table to find out since the sample from the population is distributed as a bell curve (Sharpe, Veaux and Velleman 2015).

First step is data collection, we have breath data collected, the ¯X = 25 and the total number of samples are 60.

Now we make assumptions that the population distribution follows bell curve and the center of the curve is zero mean or

Research results tell us information about data that has been collected. Within the data results, the author states the results are statistically significant, meaning that there is a relationship within either a positive and negative correlation. The M (Mean) of the data tells the average value of the results. The (SD) Standard Deviation is the variability of a set of data around the mean value in a distribution (Rosnow & Rosenthal, 2013).

## What is the Verification Principle?

The verification principle arose from a movement in the 1920’s known as Logical Positivism and, in particular from a group of philosophers known as the Vienna circle. They applied principles of science and mathematics to religious language and argued that, like human knowledge, religious language also had to be empirically verified through experiences if it were to be considered meaningful. They believed that this was the basis of all forms of empirical testing. From this, Vienna Circle established that truth and meaning can be identified as two distinct concepts when referring to religious language. Consequently, statements such as ‘God exists’ may have meaning to a believer, however, it would be a completely different matter to state

A hypothesis is an explanation that can be tested based on observation. A statistical hypothesis is testable explanation based on observation and different variables. A null hypothesis explains what the results of the experiment will be if the original hypothesis is wrong. An alternate hypothesis is the opposite result if there is or isn’t a null hypothesis.

The standard deviation is found to be 0.55. With these calculations and a confidence level of 95%, the confidence interval would be 0.2. There is a 95% certainty that the true population mean falls within the range of 14.7 to 15.1.
