We are conducting a test of the hypotheses
(H0:p=0.4)
versus
(Ha:p≠0.4)
For our test, we calculate a sample proportion of 0.28 with a sample size of 50. What is the corresponding p-value? Give your answer to four decimal places.
According to the given question, we want to test the test hypothesis as:
Against the alternative hypothesis as;
For the test, the sample proportion of 0.28 with a sample size of 50.
Therefore, and
Therefore the test statistics is define as:
we accept the null hypothesis.
Corresponding P value is determined as:
Interpretation:
As
Hence the result is not significant at we accept the null hypothesis and we can conclude that we do not have any sufficient evidence to conclude that (Ha:p≠0.4).
What is the corresponding p-value
