The cost of a laptop computer in 2007 was $1,250. In 2009, the price decreased to $1,100.

sashaice [31]

Given : The Cost of Laptop in 2007 is $1250

Given : The Cost of Laptop in 2009 is $1100

Decrease in Price of Laptop from 2007 to 2009 : (1250 - 1100) = $150

A) Percent Decrease in the Price of the Laptop from 2007 to 2009 is :

$\mathsf{\implies \frac{Decrease\;in\;Price\;of\;Laptop\;from\;2007\;to\;2009}{Price\;of\;Laptop\;in\;2007} \times 100}$

$\mathsf{\implies \frac{150}{1250} \times 100}$

$\mathsf{\implies 12\%}$

Given : Decrease in Price of Laptop from 2009 to 2010 = $165

B) Percent Decrease in the Price of the Laptop from 2009 to 2010 is :

$\mathsf{\implies \frac{Decrease\;in\;Price\;of\;Laptop\;from\;2009\;to\;2010}{Price\;of\;Laptop\;in\;2009} \times 100}$

$\mathsf{\implies \frac{165}{1100} \times 100}$

$\mathsf{\implies 15\%}$

The most important characteristic of a sample that makes it possible to generalize the results of a research study to the popula

nlexa [21]

Answer:

C. The sample is carefully screened to ensure that it contains, proportionately, people with the same demographic profiles as encountered in the population.

Step-by-step explanation:

Sampling

This is a common statistics practice, when we want to study something from a population, we find a sample of this population.

When choosing a sample, you have to be careful, to avoid choosing a biased sample.

In this question:

Option A is not correct, as this wouldnt be representative of the entire population, since there is expected to be a significant number of people without these skills.

Option B is not correct, as we would not have a sample.

Option D is not correct, as a quickly selected sample could lead to bias.

Option E is not correct, as it could also lead to bias.

So the answer is given by option C.
