1. Week 1 Tutorial: Foundation Mathematics for Business Statistics
Week 1 Tutorial: Foundation Mathematics for Business Statistics
The objective of this tutorial is for students to identify gaps in their maths knowledge early so they don’t make errors and little mistakes that will cost them marks in other assessments. Please go through the PowerPoint file “Calculator”.

2. BSTATS-KEY ASSESSMENT ITEMS
“THRESHOLD CONCEPTS”
THRESHOLD
WEEK
THRESHOLD CONCEPT 1 (TH1): Identifying relevant data, understanding measurement properties of data
WEEK 1
THRESHOLD CONCEPT 2 (TH2): Understanding Data and summarizing data
WEEK 2
THRESHOLD CONCEPT 3 (TH3): Relating variables and analyzing relationships between variables
WEEKS 3-5
THRESHOLD CONCEPT 4 (TH4): Theoretical foundation of statistical inference-Understanding events and using data to calculate the probability of occurrence of an event.
WEEK 7
THRESHOLD CONCEPT 5 (TH5): Theoretical foundation of statistical inference: Collecting samples and drawing inference
WEEK 10
THRESHOLD CONCEPT 6 (TH6): Theoretical foundation of statistical inference: Building interval estimates and constructing hypothesis for statistical inference
WEEKS 11-12
Threshold assessment system is based on identifying and testing students on key fundamental concepts that contribute to acquiring knowledge of a subject. The threshold assessment system is based on identifying specific topics/concepts and testing students in these topics in a manner such that a student can demonstrate “faultless” understanding of a threshold in terms of application of theory and analytical abilities.
You can read previous questions about thresholds on the relevant forum of the discussion board on UTS online. If your question is still unanswered then post your question.

This objective of threshold assessment and demonstration of “faultless” understanding translates to obtaining either a full score (e.g. 10/10) or zero score if student lags in either theoretical understanding or analytical abilities.
TH1-TH4 : Each of these threshold will be tested as one question with 1 to max 2 subparts; student can obtain either 10/10 OR 0/10. No part marks.
TH5-TH6: Each of these threshold will be tested as one question with 1 to max 5 subparts; student can obtain part marks for sub-parts that are correctly answered. Part-marking is allowed since there is no second opportunity for TH5 and TH6.

5. Student Resources
UPASS - is a voluntary “study session” where you will be studying the subject with other students in a group. It is led by a student who has previously achieved a distinction or high distinction in that subject, and who has a good WAM. You can sign up for U:PASS sessions in My Student Admin Note that sign up is not open until week 1, as it’s voluntary and only students who want to go should sign up
Maths Study CB Free drop-in one on one consultation tutoring on math/stats related questions 11am to 5pm on weekdays

6. Question 1: Order of mathematical operation
BIDMAS: Brackets, Indices, Division and Multiplication, Addition and Subtraction
NOTE: in b), when there is a divisor line, it instructs you to treat the quantity above the numerator as if it were enclosed in a parenthesis, and to treat the quantity below the numerator as if it were enclosed in yet another parenthesis.

7. Question 2: Converting Units of Measure
a) 12.5 hours minutes =
b) 26km/h + 4 m/s =
NOTE: To turn hours into minutes, there are 60 minutes in an hour, so multiply 12.5 by 60 and you will get 12.5 hours in terms of minutes.
NOTE: There are 1000 meters in a kilometer. So multiply 26 by 1000 to give you 26km in terms of meters. There are 3600 seconds in an hour, so to turn m/h into m/s, divide by 3600 to give you 26000m/h in terms of m/s.

8. Question 3: Square Root
REMEMBER: (from q1) when there is a divisor line, it instructs you to treat the quantity above the numerator as if it were enclosed in a parenthesis, and to treat the quantity below the numerator as if it were enclosed in yet another parenthesis.

9. Question 4: Indices Rules
NOTE: in d), mathematicians define y^0 = 1 in order to make the laws of exponents work even when the exponents can no longer be thought of as repeated multiplication. For example, (y^3)(y^5) = y^8 because you can add exponents. In the same way (y^0)(y^2)=y^2 by adding exponents. But that means that y^0 must be 1 because when you multiply y^2 by it, the result is y^2. Only y^0 = 1 makes sense here.

10. Question 5: Converting Decimals to Percentage to Fractions
NOTE: this is a very fundamental concept and often very handy to simplify and solve problems. From decimals to percentage, multiply by 100. From decimals to fractions, divide the decimal form by 1 then multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)

11. Question 6: Mathematical Notation

12. Question 7: Factorial ! If n=10, p=5 , y=0, Find n!, p! and y!
For the same values calculate p!/[(n-p)!]=
NOTE: To find out why 0!=1 go to
