1. A certain drug test has a 10% false positive rate (a positive test even if the person has not used that drug) and a 15% false negative rate (a negative test despite the person using the drug). It is known that approximately95% of people do not use the drug being tested for. If 10,000 people are given the test, complete the table with the expected results and then answer the following questions. Test Results Positive Negative Total No Drug...

Please how could you paraphrase these 2 sentences: 1. One major positive for this study is that it is observational, so no possible errors can come from the experimenter interfering with the study. A limitation that stood out to me the most in this study would be the sample size only being 167, although it is a good thing to have a wide range of ages 8 to 17, only having 167 doesn't really provide the best results or a...

A conducting rod is pulled horizontally with constant force F= 3.20 N along a set of rails separated by d= 0.480 m. A uniform magnetic field B= 0.800 T is directed into the page. There is no friction between the rod and the rails, and the rod moves with constant velocity v- 4.70 m/s Using Faraday's Law, calculate...
