<span>the factors of 8 are 1 2 4 8
the factors of 16 are1 2 4 8 16
the common factors are 1, 2, 4, 8
the GCF 8</span>
The answer is 3,000 because the 7 is larger than 5, so you round the 2 to a 3.

Answer:
95% Confidence interval of the standard deviation: 3.33 ≤ σ ≤ 8.85
Step-by-step explanation:
Sample size = 10
Degrees of freedom = 10-1 = 9
For a 95% confidence interval, we have α=0.05, which gives 2.5% of the area at each end of the chi-square distribution.
We calculate the chi-square values for a 95% confidence interval
Value of chi-square_0.975 = 2.70
Value of chi-square_0.025 = 19.02
We then evaluate [/tex] for the two values of chi-square.
Then we have:
[/tex]
With these results we can express the confidence interval as
3.33 ≤ σ ≤ 8.85
