Answer:
Option (4).
Step-by-step explanation:
Outer diameter of the hollow metallic ball = 10 centimeters
Outer radius of this ball = 
= 5 cm
Volume of the outer ball 
= 
= 
Inner radius of the hollow metallic ball = (5 - 1) = 4 cm
Volume of the inner hollow ball 
= 
Volume of the metal used in the metallic ball = 
= 
= ![\frac{4}{3}\pi [(5)^3-(4)^3]](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%5B%285%29%5E3-%284%29%5E3%5D)
Therefore, expression given in option (4) will be used to measure the volume of the hollow metallic ball.
Step 1: Calculate the 0.035 that you already know how to do.
Step 2: Calculate 1-0.035 = 0.965
Step 3: Look at the Z table and find 0.965 (or as close to this value as possible)
<span>Step 4: Look at the far left of the row containing 0.965 </span><span> 1.8</span>
<span>Step 5: Look at the top of the column containing 0.965 </span><span> 0.01</span>
<span>Step 6: Add these two values </span><span> 1.81</span>
<span>Step 6 is your z value that corresponds to that level of confidence.</span>
