The janitor calculates a p-value for the hypothesis test of approximately 0.087. Choose the correct interpretation for the p-value.

A) The p-value tells us that the probability of concluding that the defect rate is equal to 0.07, when in fact it is greater than 0.07, is approximately 0.087.
B) The p-value tells us that the true population rate of defective light bulbs is approximately 0.087.
C) The p-value tells us that if the defect rate is 0.07, then the probability that the janitor will have 27 defective light bulbs out of 300 is approximately 0.087. At a significance level of 0.05, this
Would not be an unusual outcome.
D) None of these

The p-value of 0.087 indicates the probability of observing a sample statistic as extreme as the one observed, assuming the null hypothesis is true. It does not directly tell us about the true population rate or the probability of the null hypothesis being true.
