2 30 Each family in Green Country is classified as living in an urban, rural, or suburbanlocation. During a given year, 15% of all urban families move to a suburban location, and 5% move toa rural location; also, 6% of all suburban families move to an urban location, and 4% move to a rurallocation; finally, 4% of all rural families move to an urban location, and 6% move to a suburbanlocation.a. If a family now lives in an urban location, what is the probability that it will live in an urban areatwo years from now? A suburban area? A rural area?b. Suppose that at present, 40% of all families live in an urban area, 35% live in a suburban area, and25% live in a rural area. Two years from now, what percentage of Green Country families will live inan urban area?c. What is the future population distribution of the Green Country at the steady state?

Part 1: The state of Maryland's arrest rate for marijuana possession in 2010 was the fourth highest in the nation. Public records for that year show that police arrested one out of every 250 Maryland residents for possession of marijuana. In addition, while Black people only comprised 30% of the State's population in 2010, 58% of those arrested for marijuana possession were Black. Use the following labels for events describing Maryland residents in the year 2010. M-AMP: Maryland resident was arrested for marijuana possession M-B: Maryland resident was a Black person a) What is the probability that a Maryland resident was arrested for marijuana possession in 2010? b) Use probability notation to express the cited percent values. 30% = P( 58% = P( c) Which of the values cited should be compared to determine whether race and arrests for marijuana possession in the state of Maryland in 2010 are independent?
An educational psychologist is interested in whether using a child’s own name in a story affected attention span while reading. Six children were randomly assigned to read a story under ordinary conditions (using common and generic names). Five other children read versions of the same story, but with each child’s ownname substituted for one of the children in the story. The researcher measured the amount of time (in minutes) each child spent reading the story. The results are shown in the following table. Does including the child’s namemake any difference in attention span? Test the hypothesis at an alpha set to .05, following these steps: a) write the null and alternative hypotheses; b) determine the critical value(s); c) draw the comparison distribution with rejection region(s) shaded; d)use the correct formula to compute the test statistic; e) state the statistical decision; f) state a brief conclusion.

A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 17 offspring birthed.They then observe that 12 are female.Use a sign test to test the indicated hypothesis.What is the value of "significance"
