Quizplus · Accepted Answer

A p-value is the probability of observing a sample result as extreme or more extreme than the given sample result, assuming the null hypothesis is true. However, the question does not provide information about the null hypothesis or the significance level. Therefore, it cannot be determined whether the results are statistically significant or not, and the p-value cannot be calculated. Hence, the correct answer is B (0.0) because there is no sufficient information to calculate the p-value.
