- Question Help ▼ Police often set up sobriety checkpoints-roadblocks where drivers are asked a few brief questions to allow the officer to judge whether or not the person may have been drinking. If the officer does not suspect a problem, drivers are released to go on their way. Otherwise, drivers are detained for a Breathalyzer test that will determine whether or not they will be arrested. The police say that based on the brief initial stop, trained officers can make the right decision 80% of the time. Suppose the police operate a sobriety checkpoint after 9:00 p.m. on a Saturday night, a time when traffic safety experts suspect that about 19% of drivers have been drinking. Complete parts a) through d) below. a) A statistics student is stopped at the checkpoint and, of course, has not been drinking. What is the probability that the statistics student is detained for further testing?

Shoes made of reeds, papyrus, or even leather decompose easily, leaving few or no traces. But people who don’t wear shoes have wider feet and bigger gaps between their big toe and the other four. In studying bones of the smaller toes of fossilized skeletons, scientists observed that the thickness of these bones decreased somewhere between 40,000 and 26,000 years ago. They believe the change was the result of wearing shoes. 1 Select the correct answer. Read this sentence again. In studying bones of the smaller toes of fossilized skeletons, scientists observed that the thickness of these bones decreased somewhere between 40,000 and 26,000 years ago. How does the sentence develop the author’s claim in the passage?…
- Answer these questionIn hypothesis testing, if you find significance, does that mean that your study has meaning? Explain. _______________________________________________R & A II, Chapter 11 Practice A music teacher hypothesized that singing with hand movements about math will improve the math scores of elementary school children. To test her hypothesis, the teacher obtained permission from 10 parents of Dixie Bee Elementary school children to give their children an extra 30 minutes of singing (about math) instruction at the end of the school day. The 10 children were first given a standard math test by their music teacher. Then they received 30 minutes of singing time with their music teacher, once a week, for 6 weeks. The 30 minute sessions included singing and dancing to songs about math. At the end of the 6 weeks period, the music teacher gave the children the same math test again. Below are the pretest and posttest scores for the 10 children. There were 10 questions on the math test.
