Answer with explanation:
Mean of the data set = 112
Standard Deviation of the data set =2.5
Since , 50% of data lies on both side of the mean.
Z at 50% = 0.1915
Margin of error for this data set
Margin of error=0.045(approx)

The quotient of the synthetic division problem is "f(x) = -2x² + 9x + 5" (Option C).
<h3>What is Synthetic Division?</h3>
When a polynomial division is executed using the shorthand method, using a linear factor, one is said to have executed a Synthetic Division.
The synthetic division translates to
- 2 15 -22 -15
<u>3 | -6 27 15</u>
-2 9 5 0
Citing the coefficient of the quotient of the first three numbers:
- 2, 9, 5. The last number is given as the remainder.
Hence the remainder is zero.
Given that the coefficient of the quotient are three, the interpretation is that the polynomial greatest degree is 2.
Thus,
f(x) = -2x² + 9x + 5
