The result is x^2 +x +4 -21/(x+3).

Polynomial long division tends to be easier than numerical long division because the quotient term never needs adjustment. It is always the ratio of the highest degree terms of the dividend and divisor.
See the attachment for the intermediate steps.
Answer:
Step-by-step explanation:
We know that the confidence interval for population standard deviation is given by :-
, where n= sample size
s = sample standard deviation.
and
= Chi-square critical value for degree of freedom (n-1) and significance level (
).
Given :
n= 16
Critical ch-square values for degree of freedom 15 and will be :
Then , the required 99% confidence interval for the population standard deviation will be :
Hence, the a 99% confidence interval for the population standard deviation :
