Answer:
99% Confidence interval: (0.0375,0.2099)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 97
Number of left handed, x = 12
99% Confidence interval:
Putting the values, we get:
The required confidence interval is (0.0375,0.2099).
Volume of the original sphere:
Volume = 4/3πr^3
Original sphere has a radius of 8 cm:
Volume = 4/3 * 3.14 * 8^3
Volume = 4/3 * 3.14 * 512
Volume = 2143.57 cubic cms.
Volume of smaller sphere with radius of 2 cm:
Volume = 4/3 * 3.14 * 2^3
Volume = 4/3 * 3.14 * 8
Volume = 33.49 cubic cms.
Number of balls that can be made: 2143.57 / 33.49 = 64
