Each American family is classified as living in an urban, rural, or suburban location. During a given year, 15% of all urban families move to a suburban location, and 5% move to a rural location; also, 6% of all suburban families move to an urban location, and 4% move to a rural location; finally, 4% of all rural families move to an urban location, and 6% move to a suburban location. a If a family now lives in an urban location, what is the probability that it will live in an urban area two 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, and 25% live in a rural area. Two years from now, what percent- of American families will live in an urban area? c What problems might occur if this model were used to predict the future population distribution of the United States? age

People come to relationships with different attachment styles that partially stem from the attachments they experienced with the adults raising them and partially due to experiences in other relationships in their lives. Those who have what is known as “secure” attachments are comfortable with their partners emotions, can help soothe, and make movements towards the other person in a responsive way. Among a group of 10 individuals rated as having a secure attachment style, a researcher wanted to know if, as they were first being acquainted with another person, the amount of self-disclosure made them like their person more. The data is listed in Table 6 below. Test the hypothesis at an alpha of 0.05 (where increasing scores mean higher disclosure and higher liking). If you knew the new person you are about to go on a date with had a self-disclosure rating of 4, what would you predict your likeability score would be (provide the full regression formula as well as the response)? -use…
A report in the college newsletter used the registrar's database for all the students in the school to look at majors and classes being taken this semester. The report includes the sentences:
According to the United States Census Bureau (2011 data), there are approximately 55,500,000 married couple households in the United State.

Throughout the world, women are targets of harassment, discrimination, violence, and evenmurder due to perceptions of their clothing choices. Some women are targeted because theydress to religious and some women are targeted because they do not dress religious enough.

What statistical test should beused to determine if there is a relationship between number of women’s clothing regulations andthe number of reports of social hostility? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B. What would be the appropriate statistical test? Explain your rationale.
After an earthquake, 32 homes in a remote area were checked by public safety officers before nightfall. They found that 22 of the houses had no gas, including 10 houses whose own gas lines were damaged. (A house loses its gas service if it has damage to its own line or if there is damage to the feeder line.) Of those houses that lost their gas, only 4 did not lose their electricity. Twenty-four houses in all had no electricity, the same number of them lost only their electricity as those that both lost electricity and had damage to their gas lines. How many of the houses checked did not lose either gas or electricity, and how many lost only their gas service! Students, draw anywhere on this slide!

In 2003, then U.S. Secretary of Defense Donald Rumsfeld won Britain’s Plain English Campaign 2003 Golden Bull Award for this statement: “Reports that say that something hasn’t happened are always interesting to me, because as we know, there are known knowns, there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don’t know we don’t know.” What possibility did Secretary Rumsfeld omit?
