Probability is the measure of the possible likelihood of an event to occur. In laymen terms what are the chances of a particular event to happen. Let’s say when you are flipping a coin what are the chances of its turning up head? These are the questions which are answered considering the odds and define the world of probability. The outcome of any probability related math will lie between 0 and 1. 0 means improbable while indicated certainty of the event to happen. Higher the probability of any event, more likely the event will end up occurring. The science of measuring and quantifying this numbers revolves around the world of probability. Although probability is part of modern theories of mathematics, however the roots of the same originated from the times when people are gambling. People have been highly interested in finding the odds so that they can stake themselves in better manner in the world of gambling. Probability theory revolves around the world of probability and revolves around different kind of perception and interpretation of probability. The survey is a part of 2012 National Health Interview Survey mapping all the adults in the United States, classified under the criteria of the age group.

Question 1
The requisite hypotheses based on the data that has been collected are outlined below.
Null Hypothesis: The proportion of Americans within the age group of 18-44 years who
have undergone testing for HIV is equal to 0.5 or p=0.5
Alternative Hypothesis: The proportion of Americans within the age group of 18-44 years
who have undergone testing for HIV is less than 0.5 or p<0.5
In the given a single tail test would be deployed using z statistic.
Z statistic = (P-p)/SE
P= (50080/(50080+56405) = 0.47
SE=(0.5*0.5/106485)
0.5
= 0.0015
Z statistic = (0.47-0.5)/0.0015 - -19.57
The p value associated with the above amounts to 0.00 which implies that the null
hypothesis would be rejected leading to acceptance of the alternative hypothesis. This
implies that the less than 50% of the American adults in the age group of 18-44 years are
tested for HIV virus (McDonald, 2014).
Question 2
Typically, a hypothesis tends to involve two varieties of statements known as the null and
the alternative hypothesis. The alternative hypothesis or H1 is the hypothesis or statement...
