Extracted text: Indomethacin is one type of non-steroidal anti-inflammatory drug that is given to people diagnosed with ankylosing spondylitis (or AS, a rare kind of arthritis) to suppress pain. It is observed that this medication takes effect up until 4 weeks after regular intake. However, due to medical advancement, we expect that it will take less than the reported time interval. To confirm this, a researcher gathered 15 randomly selected patients with AS, and recorded the time it took for the pain, swelling, or stiffness to be relieved after indomethacin intake (in weeks). If the true average weeks is less than 4 and we fail to reject the null hypothesis, did a type I, type II, or no error occur?
