Answer:
the P value is 45.22%
Step-by-step explanation:
The computation of the P value is as follows;
Given that
standard deviation = 14.9
mean = 675
Reduction in diameter= 673.2
Based on the above information,
We have to applied the following formula i.e.
Now the P value for -0.1208 is 0.4522 i.e. 45.22%
Hence, the P value is 45.22%
The same is to be considered
The original volume of the ballon, with radius r, is given by
V₀ = (4/3)πr³ in²
If the radius increases to (r+5) because of air input, the new volume is
V₁ = (4/3)π (r+5)³ in²
The difference in volume is the amount of air used to inflate the balloon.
The volume of air is
V = V₁ - V₀
= (4/3)π [r³ + 3r²(5) + 3r(5²) + 5³ - r³]
= (4/3)π (15r² + 75r + 125) in³
Answer: (4/3)π (15r² + 75r + 125) in³
