Suppose a group of people were tested for a disease and asked about their smoking status. Consider these results: 10 people tested positive and said they were smokers, 15 people tested negative and said they were smokers, 14 people tested positive and were nonsmokers, and 21 tested negative and said they were nonsmokers. These are summarized in the following table: Smoker Nonsmoker Positive 10 14 Negative 15 21 Consider selecting a person at random from this group. Let A denote the event that the person is a smoker and B be the event that they tested positive. Are A and B independent?

Suppose that, for each person watching a video, YouTube receives one dollar in ad revenues (P=1). Arthur is a professional video-game player. He plays the video-game "Fortnite" and uploads his video to YouTube. The number of people who will watch his video depends on Arthur's effort producing the video and increasing its quality. The number Q of viewers as a function of Arthur's effort "e" is given by the function Q= Be. Arthur's offort cost is 202. His utility equals his income minus ys effort cost. To give incentives to Arthur to create better videos and attract more viewers, YouTube decides to pay Arthur a bonus b for each person watching his video. YouTube also has an operational cost 30 Operational cost - 32 which is the cost of maintaining its internet servers and administrative staff. YouTube's profit equals the ad revenue minus the payment to Arthur and the operational cost. Find…Please no written by hand solution In 1972 the U.S. Food and Drug Administration (FDA) began requiring all aspirin manufacturers to package aspirin in bottles with child-resistant protective caps, to make it much harder for children to open the bottles and thus reduce the number of young children who died from overdosing on aspirin. (Children apparently thought the aspirin was candy.) Rather than decreasing, the number of young children who died from overdosing on aspirin actually increased. Use the Economic Way of Thinking to carefully and completely explain why requiring this safety device led to an increase in the number of children overdosing on aspirin.
- please help me with 5. Thank youADVERSE SELECTIONSomet Health Insurance Company wants to sell a health insurance product for $700 permonth. There is no requirement for healthy people to have insurance coverage. Thecompany conducts a survey to see how different populations respond to the proposed cost.People with no illnesses and disabilities, generally the young and healthy, respond that theydo not spend $700 on healthcare in an entire year, and most feel they would not waste somuch money on premiums when the chance of needing surgery or expensive healthcaretreatments is so small. However, older, sicker people think that $700 per month is a greatdeal, as most of them spend far in excess of this amount on healthcare. It seems like agreat deal for them. What will happen to the costs of the health insurance if only the older, sicker peopleenroll?A researcher wants to study about the behaviours of postgraduate students in Australia in mobile phone usage. One of the goals of the study is to analyse whether there is a relationship between the amount of time they spend using the mobile phone and their gender. What are the two variables involved to achieve that goal?
- LIVING IN SPAINJackie moved to Spain to work for a public relations firm.
