7 - Hypothesis testing Flashcards
1
Q
If the calculated probability is 0.06 and the significance level for a single tailed test is 5%, can the null hypothesis be rejected?
A
Nope, 0.06 > 0.05
2
Q
What does the significance level of a hypothesis test represent?
A
The probability of incorrectly rejecting the null H.
3
Q
What is the null hypothesis?
A
The hypothesis assumed to be correct
4
Q
What is a critical region?
A
A region which, if the test statistic falls within it, causes null H to be rejected
5
Q
What is the critical value?
A
The first value to fall inside of the critical region
6
Q
What is the actual significance level of a hypothesis test?
A
The calculated test statistic, which represents the probability of incorrectly rejecting the null hypothesis.
