Data Sufficiency:
 If m, s are the average and standard deviation of integers a, b, c, and d, is s > 0?
  1. m > a
  2. a + b + c + d = 0
  • a)
    Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
  • b)
    Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
  • c)
    BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
  • d)
    EACH statement ALONE is sufficient to answer the question asked.
  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
Correct answer is option 'A'. Can you explain this answer?

Statement 1: m > a
If a = b = c = d, the average m will be the same as a.
Since m > a, all the elements in the set cannot be the same, and therefore, s > 0.
Statement 1 ALONE is sufficient.
Eliminate choices B, C and E. Choices narrow down to A and D.

(1) The average of a, b, c, and d is 20.
(2) The standard deviation of a, b, c, and d is 5.

From statement (1) alone, we cannot determine the value of the standard deviation s. Knowing the average does not provide information about the spread of the data points.

From statement (2) alone, we cannot determine if s is less than 5. The standard deviation being 5 does not necessarily mean that it is equal to 5.

Therefore, the statements together are also not sufficient to determine if s is less than 5.
