- Cause-and-effect relationshipb. Accidental relationshipc. Common-cause factor Reverse cause-and-effect relationshipe. Presumed relationship _____ The population of certain species of animals decreases as logging in wilderness areas increases._____ The sales of sports cars increase as the school year comes to a close in June._____ The price of bread and canola oil both increase sharply after the prairies experience a drought during the growing season._____ Demand for consumer goods increases as the unemployment rate decreases.arrow_forwardRedo exercises 17 and 18 in section 8.1 of your textbook, about the small animal who lives in an area with woods and meadows, using the following data: If the animal is in the woods on one observation, then it is twice as likely to be in the woods as the meadows on the next observation. If the animal is in the meadows on one observation, then it is three times as likely to be in the meadows as the woods on the next observation. Assume that state 1 is being in the meadows and that state 2 is being in the woods. (1) Find the transition matrix for this Markov process. (2) If the animal is initially in the woods, what is the probability that it is in the woods on the next three observations? (3) If the animal is initially in the woods, what is the probability that it is in the meadow on the next three observations?arrow_forwardDoctorates The following table shows the annual number of PhD graduates in a country in various fields.
