A certain prescription medicine is supposed to contain an average of 250 parts per million (ppm) of a certain chemical. If the concentration is higher than this, the drug may cause harmful side effects; if it is lower, the drug may be ineffective. The manufacturer runs a check to see if the mean concentration in a large shipment conforms to the target level of 250 ppm or not. A simple random sample of 100 portions is tested, and the sample mean concentration is found to be 247 ppm. The sample concentration standard deviation is s = 12 ppm.   Suppose that the test statistic was -3.00. What is the p-value for this test?   Group of answer choices p-value < 0.0005 0.0005 < p-value < 0.001 0.001 < p-value < 0.0025 0.002 < p-value < 0.005
