Explain what a P -value is. What is the criterion for rejecting the null hypothesis using the P -value approach?
Explain what a P-value is. Choose the correct answer below.
A. A P-value is the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true.
B. A P-value is the value used to designate the area in either the left- or right-tail of the normal curve.
C. A P-value is the number of standard deviations that the observed proportion is from the proportion stated in the null hypothesis.
Studdy Solution
STEP 1
1. The problem involves understanding the concept of a P-value in hypothesis testing.
2. The P-value approach is used to decide whether to reject the null hypothesis.
STEP 2
1. Define what a P-value is.
2. Explain the criterion for rejecting the null hypothesis using the P-value approach.
STEP 3
A P-value is defined as the probability of observing a sample statistic as extreme or more extreme than the one observed under the assumption that the statement in the null hypothesis is true.
Correct answer: A
STEP 4
The criterion for rejecting the null hypothesis using the P-value approach is as follows: - If the P-value is less than or equal to the significance level , reject the null hypothesis. - If the P-value is greater than , do not reject the null hypothesis.
