There are many answers o this question
just think,
for example, a truck driver is asked to load a bunch of tomato crates onto his truck, which can only carry 1 tonne, how is he gonna know the number of tomato crates his truck can carry?
Answer:
Cannot create sample
Step-by-step explanation:
We are given the following in the question:
4, -2, -6, 19, 6
Formula:
where
are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 0.04 + 38.44 + 104.04 + 219.04 + 3.24 = 364.8

If we add an observation equal to the mean of given sample, then the mean and of new sample will not change.
New sample:
4, -2, -6, 19, 6, 4.2

Sum of squares of differences = 0.04 + 38.44 + 104.04 + 219.04 + 3.24 + 0 = 364.8

Thus, the variance of new sample changes.
Thus, it is not possible to create a sample.
The correct answer is: [C}: " 3 ⁻ ¹ " .
___________________________
<u>Note</u>: " 3 = 3 ¹ " .
→ " 3 ⁻ ¹ = 1 / (3 ¹) = 1 /3 =
" .
_______________________
Let us consider the remaining answer choices:
_______________________
Choice [A}: " ( - 1)³ " .
<u>Note</u>: " ( - 1)³ " = " { - 1 * - 1 * - 1 } " = " -1 " .
→ " -1 " ≠ "
" .
→ So; Choice [A} is INCORRECT.
___________________________
Choice [B]: " (- 3)¹ " .
<u>Note</u>: " ( - 3)¹ " = " -3 " .
→ " -3 " ≠ "
" .
→ So; Choice [B] is INCORRECT.
___________________________
→ The correct answer is: [C]: " 3 ⁻ ¹ . "
