- Below are summaries of two studies exploring the dangers of texting while driving. Read eachsummary and then comment on which study, 1 or 2, you think provides stronger evidence that textingwhile driving is dangerous. Explain your reasoning by laying out the facts (identify the scientific studiesbeing done, potential errors, etc.) from these two studies and implications that led you to your conclusion. Study 1: Drivers in this study were between the ages of 16 and 54, and they performed on a closedcourse, with no other cars or pedestrians present. The idea of “danger” was measured by drivers’ reactiontime—the time from seeing a flashing yellow light until they applied the car breaks. The treatment condi-tions in this study were: sending text messages, reading text messages, and a control condition in whichdrivers completely focused on the road. Study 2: Drivers in this study were long-haul truck drivers, and their behavior was recorded using severalcameras inside the cab of their…The National Association of Realtors estimates that 23% of all homes purchased in 2004 were considered investment properties. If a sample of 800 homes sold in 2004 is obtained and it was noted that 248 homes were to be used as investment property, would this be unusual? Answer either "yes" or "no" and provide the justification for your answer.Kentville, a community of 10,000 people, resides next to a krypton mine, and there is a concern that the emission from the krypton smelter have resulted in adverse effects. Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6 What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes? How many times the chance of dying of Kryptonosis compared to dying of accidents ? How many times the chance of dying of Kryptonosis compared to Other causes?
- In a recent submission to a Joint Select Committee of Parliament, the National Consumers' League said “In reality, cow’s milk especially processed cow’s milk, has been linked to a variety of health problems, including: mucous production, haemoglobin loss, childhood diabetes, heart disease, arteriosclerosis, arthritis, kidney stones, mood swings, depression, irritability, allergies.” Researchers know this to be true, though the Committee rejected the submission. Suppose that 34% of the population has mood swings, allergies, irritability and depression (MAID) and is known to consume dairy products. Also, 80% of the populace consumes dairy products. Suppose a randomly chosen dairy products user is tested, what is the probability this person has MAID? Select one: a. 0.425 b. 0.460 c. 0.140 d. 0.272A cohort study was conducted over five years among 200 trial attorneys and general practice attorneys after stringent tort law reform, to see how many would develop heart conditions over time. In total, 50 attorneys developed heart disease. It was found that 40 who developed disease practiced trial law, while 10 who developed disease did not practice trial law. One hundred (100) who did not develop disease also did not practice trial law, and 50 who did not develop disease practiced trial law.
