Answer:
There were 120 yellow water bottles in the shipment
Explanation:
Multiply 400 by 30% to find out how many water bottles came in yellow.
400 • .30 = 120
So, 120 were yellow.
        
                    
             
        
        
        
So lets do it like this:
z = (X-Mean)/SD 
<span>z1 = (8-12)/2 = - 2 </span>
<span>z2 = (16-12)/2 = + 2 </span>
<span>According to the Empirical Rule 68-95-99.7 </span>
<span>Mean more or less 2SD covers 95% of the values </span>
So t<span>he percentage of data points falling between 8 and 16 = 95%
</span>I hope this can help
