- A psychologist is concerned about the health of veterans returning from war. She examines 36 veterans and assesses whether they show signs of post-traumatic stress disorder. What is the population of interest? All veterans with post-traumatic stress disorder All veterans returning from war The 36 veterans returning from war The veterans returning from war showing signs of post-traumatic stress disorder statistical power of 95% implies that it is very likely that H0 will be rejected if it is not true. the chance that the alternative hypothesis is true is 95%. the p-value for the study will be 5%. H0 is probably false.Wendy needs to get to an airport from a hotel. There is 0.19 chance that she calls a cab, there is 0.26 chance that she gets a Uber. If she cannot get a cab or Uber, she will take a shuttle. If she calls a cab, there is 0.19 chance that she could miss the flight. If she gets a Uber, the chance of missing flight is 0.34. If she takes the shuttle, the chance is 0.32. If Wendy misses the flight, what is the probability that she called a cab? (Round your answer to three decimal places)According to the Chronicles of Contrived Statistics (March, 2016), the probability that Elon Musk will offer you a free trip into space in the next month is 31%. The probability that either Elon Musk will offer you a free trip to space or that scientists will begin sales of pet aliens next month is 45%. Finally, they list that probability of both happening in the next month is 28%. What is the probability that scientists will begin sales of pet aliens next month? Answer in decimal form.

- A researcher gathered a sample of participants who volunteered for a studying of phobias. She measured anxiety level of participants as they viewed photos of spiders and again when they viewed puppies. Which statistical test is appropriate for this study and why?Some electronic devices are better used than new: The failure rate is higher when they are new than when they are six months old. For example, 43.00% of the personal music players of a particular brand have a flaw. If the player has the flaw, it dies in the first six months. If it does not have this flaw, then only 3.000% fail in the first six months. Yours died after you had it for three months. What are the chances that it has this flaw?There was a baseball game between Oscar and Gabe. The chance of Oscar winning is 3/5 (60%). The chance of Gabe winning is 2/5 (40%). This game wasn't a one game competition. It's the best of 5 series. This means the first person to win 3 games is the overall champion. What's the probability (% is best) that Oscar is the champion? Don't answer this question as Oscar with a 60% chance and Gabe as a 40% chance. Also, don’t use the equation for finding multiple events for probability.
