What does p0 mean in statistics?

What does p0 mean in statistics?

If the alternative hypothesis is Ha: p > p0 (greater than), then “extreme” means large or greater than, and the p-value is: • The probability of observing a test statistic as large as that observed or larger if the null hypothesis is true.

How do you find p0 in statistics?

If your test statistic is positive, first find the probability that Z is greater than your test statistic (look up your test statistic on the Z-table, find its corresponding probability, and subtract it from one). Then double this result to get the p-value.

How do you describe proportion in statistics?

A population proportion is a fraction of the population that has a certain characteristic. For example, let’s say you had 1,000 people in the population and 237 of those people have blue eyes. The letter p is used for the population proportion, so you would write this fact like this: p = 237/1000.

What is the probability of type I error?

The probability of making a type I error is α, which is the level of significance you set for your hypothesis test. An α of 0.05 indicates that you are willing to accept a 5% chance that you are wrong when you reject the null hypothesis. The probability of rejecting the null hypothesis when it is false is equal to 1–β.

What is H1 and H0?

Alternative Hypothesis: H1: The hypothesis that we are interested in proving. Null hypothesis: H0: The complement of the alternative hypothesis. This is the probability of falsely rejecting the null hypothesis. Type II error: do not reject the null hypothesis when it is wrong.

What does H1 mean?

H1 may refer to the first half of the business year, while H2 refers to the second half.

What is the difference between H0 and Ha?

H0 is called the null hypothesis and HA is called the alternative hypothesis. The union of null and alternative hypothesis defines a hypothesis H ∈ Θ=Θ0 ∪ ΘA called the maintained hypothesis. A hypothesis is called simple if it completely specify the probability distribution and otherwise com- posite.
