The following is the setup for this hypothesis test:
H0:p=0.70
Ha:pā 0.70
In this example, the p-value was determined to be 0.041.
Come to a conclusion and interpret the results for this hypothesis test for a proportion (use a significance level of 5%)
Select the correct answer below:
A: The decision is to reject the Null Hypothesis.
The conclusion is that there is enough evidence to reject the claim.
B: The decision is to fail to reject the Null Hypothesis.
The conclusion is that there is not enough evidence to reject the claim.
