Answer:
-8
Step-by-step explanation:
Answer:
B. Hannah is likely to be incorrect because 9 is not contained in the interval.
Step-by-step explanation:
She construct a 99% confidence interval for the difference between means and gets the interval (0.4, 8.0).
This means that there is 99% confidence that the true difference between means is within this interval.
The left 1% corresponds to the tails of the distribution: there is 0.5% probability that the difference between means is below 0.4 and 0.5% probability that the difference between means is above 8.0.
As she claims that 9 hours is the true difference, we can say that there is less than 0.5% that she is correct. In others words, is likely to be incorrect.
Answer: <em>1.1 × 10⁸ cm³</em>
Explanation:
1) Since the ball is spherical, you use the volume formula for a sphere, which is:
Volume = [4/3] π r³
2) r is the radius, which is given and is equal to 3×100cm = 300cm
3) Pluging in the value of r, you get:
Volume = [4/3] π (300 cm)³ = 113,097,335.53 cm³
4) Since, r = 3×100 cm has two significant figures, the result must show only two significant figures.
So, using scientific notation, the right answer must be reported as:<em> 1.1 × 10⁸ cm³</em>
