Many adults owe money from their college loans for years into their professional careers. a newspaper would like to estimate the

proportion of all adults in the city who have debts from college loans. to collect data, a random sample of 300 young adults between the ages of 25 and 35 is asked, "do you have more than $5,000 in current college debts?" 68% of those sampled reported that they do have more than $5,000 in college-related debts. how might this sample be biased in obtaining an estimate of all adults in the city who have college debts?

Because only young adults were sampled, undercoverage bias may cause the newspaper to overestimate the proportion of all adults who have college debts.

<h3><u>What is bias in sampling?</u></h3>

When a sample is chosen in statistics, sampling bias is a bias that causes some individuals of the target population to have a lower or greater sampling probability than others. As a result, not every person or event was equally likely to have been chosen, resulting in a biased sample of a population (or non-human variables).

If this is not taken into consideration, results may be incorrectly attributed to the sampling procedure rather than the phenomenon being studied. Although some people identify sampling bias as a distinct sort of prejudice, sampling bias is typically categorized as a subtype of selection bias, sometimes referred to as sample selection bias.

NARA [144]

Answer:

B. The payback is approximately three years

Explanation:

The computation of payback period for this equipment purchase is shown below:-

<u>Year              Cash flow          Cumulative cash flow</u>

0                   -$600,000             -$600,000

1                     $250,000              -$350,000

2                    $200,000              -$150,000

                 ($250,000 - $50,000)

3                    $150,000                  0

                 ($200,000 - $50,000)

4                    $100,000                $100,000

                  ($150,000 - $50,000)

5                    $50,000                  $150,000

         ($100,000 - $50,000)

Here, Cumulative cash flow in the year o is -$600,000 and as we can see that cumulative cash flow in year 3 is 0.

Therefore the payback period lies in 3 years.

Suppose you have the following information on Sam's budget. Sam has a yearly budget of $2000 to spend on consuming concert ticke
AleksAgata [21]

Answer:

Bundles                           A           B           C           D

Concert Tickets              80         60         20          0

Books                              0          50        150        200

Explanation:

Since each concert ticket costs $25,

  • if Sam spends $2,000 on concert tickets, he will purchase 80 tickets
  • if he spends $1,500 on concert tickets, he will purchase 60 tickets
  • if he spends $500 on concert tickets, he will purchase 20 tickets

Since each concert ticket costs $10,

  • if Sam spends $2,000 on books, he will purchase 200 books
  • if he spends $1,500 on books, he will purchase 150 books
  • if he spends $500 on books, he will purchase 50 books

goldenfox [79]

No, there is not any requirement of recording when the fair value of bonds decreases to $6000000 on December 31 of the current year.

Given that Starbucks purchased bonds with $ 7 million face value at par for cash on July 1 of the current year and the bonds pay 7 percent interest the following June 30 and December 31 and mature in three years.

We are required to tell whether there is requirement of any recording when the fair value of bonds decreases to $6000000 on December 31 of the current year.

A bond is basically a debt security, similar to an IOU and borrowers issue bonds to raise money from investors willing to lend them money for a certain amount of time. When we buy a bond, we are lending to the issuer, which may be a government, municipality, or corporation.

There is not any requirement of any recording when the fair value decreases to $600000 because it is not affecting our books of accounts because in our books they are recorded at face values.

Hence there is not any requirement of recording when the fair value of bonds decreases to $6000000 on December 31 of the current year.

A rectangular floor measures $a$ feet by $b$ feet, where $a$ and $b$ are positive integers with $b &gt; a$. An artist paints a r
DENIUS [597]

The number of possibilities that are there for the ordered pair is 2.

<h3>Calculation and Parameters
</h3>

Because the unpainted part of the floor covers 1/2 of the area, then the painted rectangle covers 1/2 of the area as well.

Given that the border width is 1 foot, the dimensions of the rectangle are a-2 by b-2.

Making an equation:

ab= 2((a-2)(b-2))

ab= 2ab-4a-4b+8

ab-4a-4b+8=0

If we apply Simon's Favorite Factoring Trick,

ab-4a-4b+16= 8

(a-4)(b-4)= 8

Since b > a, then we have the possibilities

(a-4) = 1 and (b-4) = 8, or (a-4) = 2 and (b-4) = 4.

(5, 12) or (6,8) which gives us 2 possibilities.

Aleksandr [31]

Early personal computer users remember the cumbersome, user-unfriendly "DOS" system. When Apple introduced System 1 and Microsoft introduced Windows, both of which were much easier to use, these new products diffused rapidly because of their relative advantage .

Option A

<u>Explanation: </u>

A product's dominance and market appeal over similar items. A competitive advantage is usually accomplished by giving better value to customers through either reducing prices or delivering added quality and service that justify higher costs.

That idea is based on consumer brand and product perceptions and does not necessarily reflect the actual characteristics of this product or service. The definition helps companies to consider that customers would choose to use this product or whether a rival would rather remain faithful to the already existing product.
