Assume you were testing the hypotheses Ho: p = 0.25 vs. Hai p> 0.25 with a significance level of 0.05. The p-value for the test was calculated to be 0.0048. Which of the following statements is correct? O a. The p-value tells us that if the population proportion is 0.25 , then the probability of observing the test statistic actually obtained or higher is 0.0048. O b. The p-value tells us that the true population proportion is 0.0048. O. The p-value tells us that the probability of concluding that the null hypothesis is 0.25, when in fact it is greater than 0.25, is 0.0048. O d. The p-value tells us that the null value 0.25 is significantly higher than the sample value, using a significance level of 0.05.
