University of Phoenix Material Week One Practice Problems Prepare a written response to the following questions. Chapter 1 12. Explain and give an example for each of the following types of variables: a. Equal interval: Is the numeric variable in which differences between values correspond to differences in the underlying thing being measured (Aron et al., 2013). In other words if the difference between two successive categories are the same then they are an equal interval.
Use the report pages below to record your data. Answer questions A-G found on pages 46 and 47. Name: _________________________ Lab 2 Report Data: Data Table 1: Length Measurements | Object | Length (cm) | Length (mm) | Length (m) | CD or DVD | 12.1 cm | 121 mm | .121 m | Key | 5.1 cm | 51 mm | .051 m | Spoon | 16.1 cm | 161 mm | .161 m | Fork | 18.5 cm | 185 mm | .185 m | NOTE: The instructions indicate to measure the objects to “one degree of uncertainty.” The degree of uncertainty is a property of the instrument used. All three recorded values will have the same precision. On page 29 is the explanation of uncertainty.
2.12 b. 1.734 c. -1.740 d. 1.740 ANSWER: d -same process but now go to one tailed α=0.05 and dof = 17 4. Read the t statistic from the table of t distributions and circle the correct answer. A one-tailed test (lower tail), a sample size of 10 at a .10 level of significance; t = a. 1.383 b.
KNOWLEDGE ASSESSMENT - M3.40 UNDERSTANDING SUPPORT SERVICES OPERATIONS This is a suggested template that BIFM Training encourages candidates to use to ensure they answer all elements of this assessment, and remember how the marking system works. You do not have to use this template but you must cover all the elements and use the headings in bold below. The assessment criteria are in your course handbook, and it contains more guidance than here. The suggested word count range is a minimum of 1200 words and up to about 2000 words. The pass mark is 50% and you will have to achieve a minimum number of marks in each section.
Task III A. Use the above situation to complete parts A1 through A4: 1. Provide an algebraic representation of the account balance (y) for each of the two savings plans. X= Months Y= Account Balance Saving Plan A (Y2) with initial balance of 400 Y1 = (20)X+ 400 Saving Plan B (Y2) with initial balance of 600 Y2= (10)X + 600 2. Solve the system of equations algebraically to determine when the two savings plans yield identical balances and state this balance.
The table shows that there is no huge difference in numbers. Whether the face was black or white, the results were very similar and in close range. The standard deviation was also around the same range for both experiments. It seems as if there were no signs of racism in this

The Metric System( One goal of the metric system is to have a single unit for any physical quantity; another important one is not needing conversion factors when making calculations with physical quantities. All lengths and distances, for example, are measured in meters, or thousandths of a meter (millimeters), or thousands of meters (kilometers), and so on. There is no profusion of different units with different conversion factors, such as inches, feet, yards, fathoms, rods, chains, furlongs, miles, nautical miles, leagues, etc. Multiples and submultiples are related to the fundamental unit by factors of powers of ten, so that one can convert by simply moving the decimal place: 1.234 meters is 1234 millimeters, 0.001234 kilometers, etc. The use of fractions, such as 2⁄7 of a meter, is not prohibited, but uncommon, as it is generally not necessary.
If the law is changed, eighteen year olds will substitute the first year driving statistics for sixteen year olds. The same amount of accidents will still occur, only the age will change. All first year drivers need time to practice driving skills or there will never be time to learn. It’s better to have a sixteen year old getting this practice while closer to home, then an eighteen year old getting the practice while they are away at college. Hang It Up Assignment: Write an essay in which you argue for or against prohibiting cell phones in school.
There are different posted speed limits for different areas depending on how much the traffic is. Some larger roadways have median to divide opposite travel lanes due to high speed limit or high traffic volume. When I was in high school, I need a car to drive to the closest restaurant or other shops. It took me ten minutes to drive there. My high school was thirty minutes away from my house by driving.
