Answer:

a. False

b. False

c.False

d. True

Explanation:

Statement A is false because a representative sample can be obtained by asking viewers who call into an 800 number.  The sample is formed from their voluntary response and would likely  be biased. Among the population, there would be a strong opinion due to the type of invitation given. Thus, it could not be a representativeof the population.

Statement B is false because there are more questions in the survey, also, the time taken by the respondents to answer the question increases, this hereby reduces the rate. Thus, it is clear that there isa chance for non-response bias.

Statement  C is false because the large sample size does not indicate the validity of the survey. However, the resultsb of the survey may be biased if the large sample is not the representative of the population

Statement D is True

Blossom Company purchased machinery with a list price of $88000. They were given a 10% discount by the manufacturer. They paid $
frez [133]

Answer:

$5,450

Explanation:

Data provided in the question:

List price of the machinery = $88,000

Discount offered = 10%

Amount of discount = 10% of $88,000

= 0.1 × $88,000

= $8,800

Shipping paid = $400

Sales tax = $4,900

Useful life = 10 years

Residual value = $30,000

Now,

Total cost of the machine = List price - Discount + Shipping + sales tax

= $88,000 - $8,800 + $400 + $4,900

= $84,500

Annual depreciation using straight line method is given as:

= \frac{\textup{Total cost - Residual value}}{\textup{Useful life}}

= \frac{\textup{84,500 -30,000 }}{\textup{10}}

= $5,450
