Sometimes the symbol ∅ is used to distinguish "null" from 0
The symbol H 0 is the abbreviation for the null hypothesis, the small zero stands for null

the opposite of the research hypothesis. The null hypothesis states that any effects observed after treatment (or associated with a predictor variable) are due to chance alone. Statistically, the question that is being answered is "If these samples came from the same population with regard to the outcome, how likely is the obtained result?"
A right tailed test (sometimes called an upper test) is where your hypothesis statement contains a greater than (>) symbol. In other words, the inequality points to the right. For example, you might be comparing the life of batteries before and after a manufacturing change. If you want to know if the battery life is greater than the original (let’s say 90 hours), your hypothesis statements might be:
: No change (H0 = 90).
: Battery life has increased (H1) > 90.

When taking generator biases into account we now see that null hypothesis cannot be rejected for , while in the previous test we rejected it. The only one character the null hypothesis we can reject for in overall statistics is .
From the table above we see there are biases on both particular positions and in total. For example,character is biased on password positions 4 and 5 and in overall statistics (pos 1-8). On contrarywe cannot reject null hypothesis for character .

It is not necessary (or even desirable) to use the words "hypothesis" or "null hypothesis", since these are usually implicit if you clearly state your purpose and expectations.

In general, a p-value is the probability that the test statistic would "lean" as much (or more) toward the alternative hypothesis as it does if the real truth is the null hypothesis.
Left Tailed Test or Right Tailed Test
Every hypothesis test contains a set of two opposing statements, or hypotheses, about a population parameter. The first hypothesis is called the denoted H0. The null hypothesis always states that the population parameter is to the claimed value. For example, if the claim is that the average time to make a name-brand ready-mix pie is five minutes, the statistical shorthand notation for the null hypothesis in this case would be as follows:
In a hypothesis test, you have to decide if a claim is true or not
On the other hand, the null hypothesis is straightforward -- what is the probability that our treated and untreated samples are from the same population (that the treatment or predictor has no effect)? There is only one set of statistical probabilities -- calculation of chance effects. Instead of directly testing H, we test H. If we can reject H, (and factors are under control), we can accept H. To put it another way, the fate of the research hypothesis depends upon what happens to H.

The null hypothesis, symbolH0, is the statement that nothing is going on, that there is noeffect, “nothin’ to see here. Move along, folks!” Itis an equation, saying that , the proportion in the population(which you don’t know), equals some number.

The inferential statistics do not directly address the testable statement (research hypothesis). They address the . Statistically, we test "not." Here are the null hypotheses:

How do you know which hypothesis to put in H0 and which one to put in Ha? Typically, the null hypothesis says that nothing new is happening; the previous result is the same now as it was before, or the groups have the same average (their difference is equal to zero). In general, you assume that people’s claims are true until proven otherwise. So the question becomes: Can you prove otherwise? In other words, can you show sufficient evidence to reject H0?
