A company wants to test a claim concerning the specificity of their vaccination. They are testing the null hypothesis that the specificity is 75% against the alternative that the specificity is less than 75%. The p-value for the hypothesis test was determined to be 0.002. Which of the following is a correct interpretation of this p-value? The null hypothesis would not be rejected at either the 0.05 or 0.01 level The null hypothesis would be rejected at a 0.01 level but not at a 0.05 level. The null hypothesis would be rejected at both the 0.05 and 0.01 levels. The null hypothesis would be rejected at a 0.05 level but not at a 0.01 level.
