Hypothesis Testing

Question 1

What is H0?

Answer 1

Null hypothesis: hypothesis that you assume to be correct.

Question 2

Define hypothesis:

Answer 2

A statement made about the value of the population parameter.

Question 3

What does ‘p’ represent?

Answer 3

The probability and the population parameter you test.

Question 4

What is H1?

Answer 4

The alternate hypothesis, which tells you about the parameter if your assumption is wrong.

Question 5

What is the binomial distribution (as a formula) for a test statistic?

Answer 5

B(n,p)

Question 6

What is a one-tailed test?

Answer 6

Hypothesis test with an alternative hypothesis in the form H1:p…

Question 7

What is a two-tailed test?

Answer 7

Hypothesis test with an alternative hypothesis in the form H1:p≠…

Question 8

What is the significance level?

Answer 8

A given threshold. If the likelihood of less than a given threshold, then you reject the null hypothesis.

Question 9

Define a test statistic:

Answer 9

The result of an experiment, which is used to test a hypothesis about a population, that is calculated from a sample.

Question 10

Define a critical region:

Answer 10

A region of the probability distribution which, if the test statistic falls within it, would cause you to reject the null hypothesis.
