t the best 70 from among the applicants, the company gives a test that covers mechanical skill, manual dexterity, and mathematical ability. The mean grade on this test turns out to be 60, and the scores have a standard deviation of 6. Can a person who scores 84 count on getting one of the jobs?

Answer:

  • <em>As explained below, given that the score of the person is among the 0.03125 fraction of the best applicants, </em><u><em>he can count on getting one of the jobs.</em></u>

<em></em>

Explanation:

The hint is to use <em>Chebyshev’s Theorem.</em>

Chebyshev’s Theorem applies to any data set, even if it is not bell-shaped.

Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean.

For this sample you have:

  • mean: 60
  • standard deviation: 6
  • score: 84

The number of standard deviations that 84 is from the mean is:

  • k = (score - mean) / standar deviation
  • k = (84 - 60) / 6 = 24 / 6 = 4

Thus, the score of the person is 4 standard deviations above the mean.

How good is that?

Chebyshev’s Theorem states that at least 1−1/k² of the data lie within k standard deviations of the mean. For k = 4, that is:

  • 1 - 1/4² = 1 - 1/16 = 0.9375

  • That means that half of 1 - 0.9375 are above k = 4: 0.03125

  • Then, 1 - 0.03125 are below k = 4: 0.96875

Since there are 70 positions and 1,000 aplicants, 70/1,000 = 0.07. The compnay should select the best 0.07 of the applicants.

Given that the score of the person is among the 0.03125 upper fraction of the applicants, this person can count of geting one of the jobs.

What Does Sales Revenue Mean?

Sales revenue is the money a business makes from selling products or offering services. Sales and revenue can, and frequently are, used interchangeably to refer to the same thing in accounting. It is significant to remember that revenue does not always equate to money received. One part of sales revenue may be paid in cash, and the other part may be paid on credit using methods like accounts receivable.

Either the gross revenue total or the net revenue amount can be used to represent sales revenue on the income statement. All deductions for product returns, the potential for undelivered items, and the cost of bad debt are all included in net revenue.

nevsk [136]

Answer:

Explanation:

Begging Allowance for doubtful account is P1,500 (96,000 - 94,500). Ending balance of Allowance for doubtful account is P3,000 (P108,000 -P105,000). We can now work back the provision for doubtful accounts that the company has made during 2008.
