The answer is 1210.4
It is 1210 if rounded.
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
Domain: x values
Range: y values
The relation would need to have (2, y) and (4, y). And also (x, 2) and (x, 8)
See which ones match
Solution: B
Answer:
Step-by-step explanation:
When increasing the power of an integer by another power, you should multiply both powers to find the total power that the integer should be raised to. In this case therefore:
= 3 * 2
= 6
So the numerator will be 8⁶
When dividing the same integers raised to powers, you should subtract the power of the divisor from the power number being divided.
In this case therefore, you are to subtract (-5) from 6 (calculated in first part).
= 6 - (-5)
= 6 + 5
= 11
Another way of writing the above will therefore be: 8¹¹.
