Consider the following statement:
For all integers a and b, if a 0 (mod 6) and b #0 (mod 6), then
ab #0 (mod 6).
Which of the following statements are true? (select all that apply)
Original statement
✓ Contrapositive
Converse
Negation
☐ None of the statements are true
Proposition: If m is an odd integer, then m + 6 is
an odd integer.
Proof: For m + 6 to be an odd integer, there must
exist an integer n such that
m+6=2n+1.
Subtracting 6 from both sides, we see that
m = 2n+1-6
=
= 2n― 6+1
= 2(n − 3) + 1.
Since the integers are closed under subtraction,
then n-3 € Z. Hence, the last equation implies
that m = = 2q+1 where q = n = 3. This proves
-
that if m is an odd integer, then m + 6 is an odd
integer.
Based upon the Reading assignment and the Elements of Style >>, which of the
following is the most significant error in the proof?
The proof does not use complete sentences
The proof contains a sentence that begins with a mathematical symbol
The proof uses cumbersome notation
The proof contains a variable used for more than one object
The proof is written backwards
The proof uses an example to prove the general case
Suppose that you want to estimate the mean monthly gross income of all households in your local community. You decide to estimate this population parameter by calling 150 randomly selected residents and asking each individual to report the household’s monthly income. Assume that you use the local phone directory as the frame in selecting the households to be included in your sample.
What are some possible sources of error that might arise in your effort to estimate the population mean?
