The state and local police departments are trying to analyze crime rates so they can shift their patrols from decreasing-rate areas to areas where rates are increasing. The city and county have been geographically segmented into areas containing 5,000 residences. The police recognize that not all crimes and offenses are reported: people do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,000 of the 5,000 residences for data on crime. (Respondents are guaranteed anonymity.) Here are the data collected for the past 12 months for one area:

The state and local police departments are trying to analyze crime rates so they can shift their patrols from decreasing-rate areas to areas where rates are increasing. The city and county have been geographically segmented into areas containing 6,000 residences. The police recognize that not all crimes and offenses are reported: people do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,200 of the 6,000 residences for data on crime. (Respondents are guaranteed anonymity.)

- The state and local police departments are trying to analyze crime rates so they can shift their patrols from decreasing-rate areas to areas where rates are increasing. The city and county have been geographically segmented into areas containing 5,200 residences. The police recognize that not all crimes and offenses are reported. People do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time. Among other reasons.

Demand can be low, average, or high, with the estimated probabilities being 0.25, 0.40, and 0.35, respectively. A small facility is expected to earn an after-tax net present value of just $18,000 if demand is low. If demand is average, the small facility is expected to earn $75,000; it can be increased to medium size to earn a net present value of $60,000. If demand is high, the small facility is expected to earn 75,000 and can be expanded to medium size to earn $60,000 or to large size to earn $125,000. A medium-sized facility is expected to lose an estimated $25,000 if demand is low and earn $140,000 if demand is average.

Until 2010, the school had experienced strong growth, but since 2013 the enrolment numbers for Year 7 have been less than half of what they were in 2010. The Selena Valley is 50 minutes east of Melbourne and has had a recent influx of young families, but prior to this influx it was a small area with solid growth figures. Selena Valley High School is a coeducational institution with strong links to the local area in terms of apprenticeships and vocational education. The enrolment numbers for 2016 were 378 students from Years 7 to 12. Answer the following questions. 1. What is the major issue Selena Valley High School faces as of 2018 in terms of its customer base? 2. Identify whether each of the following factors is part of the internal or external operating environment of Selena Valley High School, and describe the effect each of these could have on the marketing…arrow_forward

- Use the following to answer questions 21 and 22. A shoe factory owner plans to open two new shoe factories in a few months. These factories will be opening in the same city. The owner wants to find out whether a biweekly pay cycle increases productivity compared to a weekly pay cycle. So the factory owner decides he will open one of the two factories using a weekly pay cycle, and the other using a biweekly pay cycle, then he will compare productivity levels between the two factories 6 months after they start production. In the above example, what is the independent variable? a.) Location of the factories. b.) Productivity levels after 6 months. c.) Pay cycle. d.) There is no independent variable. In the above example, what is the dependent variable? a.) Location of the factories. b.) Productivity levels after 6 months. c.) Pay cycle. d.) There is no dependent variable.arrow_forwardSmall City currently has 1,092,000 square feet of office space, of which 819,000 square feet is occupied by 3,000 employees who are mainly involved in professional services such as finance, insurance, and real estate. Small City’s economy has been fairly strong in recent years, but employment growth is expected to be somewhat lower during the next few years, with projections of an increase of just 118 additional employees per year for the next three years. The amount of space per employee is expected to remain the same. However, a new 91,800 square foot office building was started before the recession and its space is expected to become available at the end of the current year (one year from now). No more space is expected to become available after that for quite some time. Required: a. What is the current occupancy rate for office space in Small City? b. How much office space will be absorbed each year for the next three years? c. What will the occupancy rate be at the end of each…arrow_forward
