Complete the following problems within theWord document (do not submit other files). Show your work for problem sets that require calculations. Ensure that your answer to each problem is clearly visible. (You may want to highlight your answer or use a different type color to set it apart.)
Submit the document to your instructor by Sunday, 11:59 p.m. central time.
Problem Set 1.1: Order of Operations
Criterion: Apply the appropriate order of operations to solve equations.
Instruction:Apply order of operations rules and solve each of theseequations:
a.
b. (8 + 42 – 4)/5
c. 8 – 2 * 3 + 4/2
d. 40 – 6 * 5 – 2
e. – 2.
Note: To insert a square root symbol (
), click the Inserttab, and in the Symbols section, click Equation. (If Equation is grey and unresponsive, open a new document and complete your work there.) Next, click Radical and choose the best option.The square root will appear inside a frame (see picture at right). To enter numbers into the square root, click the dottedline box. When done, click outside of the frame. Then, you can copy and paste the work where you like.
Problem Set 1.2: Scales of Measurement
Criterion: Identify appropriate scales of measurement for stated variables.
Instruction:Identify the highest possible scale (nominal, ordinal, interval, or ratio) for the following:
a. Preferred political party.
b. Number of children.
c. Number of sodas you drank today.
d. Temperature in Fahrenheit.
