When probability value (p-value) is greater than alpha value, we fail to reject the null hypothesis.
Probablity value is the probability of obtaining an answer equal to or more extreme than the observed value.
Alpha value is the level of significance. It's the value set that determines if a result is statistically significant, or in other words, if it's not likely to have occurred simply due to chance. Alpha value is usually 5%.
There are two hypotheses when we conduct a hypothesis test: the null hypothesis and the alternative hypothesis.
The null hypothesis acts as a default position. It's usually an assumption that there is no relationship between two events or that a treatment has no effect. In most legal systems, the null hypothesis would be that the defendant is innocent.
The alternative hypothesis is what we would assume if we reject the null hypothesis. We reject the null hypothesis when the probability value is less than the alpha value.

What happens as the value of n increases and the probability of success remains the same?
It depends on your equation. Your equation will tell the proportionallity and then will we be able to tell what will happen to the other variables and or just one variable.
Is 7 less than or greater than the absolute value of -3?
greater as the absolute value of -3 is 3
Could the value of the variable be greater than 12.50?
The unknown value of the variable could be greater, less or even equal to 12.50
What is a graph for absolute value?
Go to the Wolfram Alpha site and type the following in the input box: |x|
Can a function have a limit at every x-value in its domain?
Yes, that happens with any continuous function. The limit is equal to the function value in this case.Yes, that happens with any continuous function.

What is Hypothesis Testing of Alpha Value?
Probability of rejecting a true null hypothesis; that is, the alpha value or risk you are willing to take probabilistically speaking.
Is alpha the probability that the test statistic would assume a value as or more extreme than the observed value of the test?
Alpha is the probability that the test statistics would assume a value as or more extreme than the observed value of the test, BY PURE CHANCE, WHEN THE NULL HYPOTHESIS IS TRUE.
Can a joint probability have a value greater than 1?
A joint probability can have a value greater than one. It can only have a value larger than 1 over a region that measures less than 1.
What is a Alpha Value?
The level of significance; that is the probability that a statistical test will give a false positive error.
Which value shows a greater probability that the result did not occur by chance 0.05 or 0.001?
In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.In the context of significance tests, the value of 0.001 indicates a lesser likelihood that the event occurred by chance, that is a greater probability that it did not occur by chance.
The expected value is what kind of aspect of how probability distribution is characterized?
Expected value is the outcome of confidence of how probability distribution is characterized. If the expected value is greater than the confidence interval then the results are significant.
What percent probability is associated with a z-value of 1.3?
None. The probability of a continuous variable taking any particular value is always zero. The probability is greater than zero only when an interval (or range) is specified.
Are fractions and probability the same?
NO, but that is a great question since probability is often expressed as a fraction. Here is the difference. If P(x) is the probability that even x happens, this value must be between 0 and 1. So fractions such as 1/2 or 2/1112 are all fine. Many fractions, such as 4/3 cannot be a probability since they are greater than one. Similarly, -1/2 cannot be a probability value since it is less than 0/
A cumulative frequency distribution would provide?
The cumulative frequency or the probability of an observed value being less than or equal to a given value. By extension, it would also give the probability of a greater value being observed.
Why not simply use the mean value of the regressand as its best value?
Variance" is a mesaure of the dispersion of the probability distribution of a random variable. Consider two random variables with the same mean (same aver-age value). If one of them has a distribution with greater variance, then, roughly speaking, the probability that the variable will take on a value far from the mean is greater.
What happens when p value is equal to alpha value?
You chose whether or ot to reject the null hypothesis. Or you repeat the experiment.
Which is not a possible vaule for a probability?
Probability value can only be real number between 0 to 1, therefore, it cannot be greater than 1 or less than 0 or a complex number.
