Roy has the highest score of 97.5% as a percent. Leas is 94%.
        
             
        
        
        
Using the normal distribution, it is found that the correct option is:
- P(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

- It measures how many standard deviations the measure is from the mean.  
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
- Mean of 20 ounces, hence  . .
- Standard deviation of 2.3 ounces, hence  
P(Y < 16) is the <u>p-value of Z when X = 16</u>, hence:



 has a p-value of 0.041.
 has a p-value of 0.041.
This is valid for the entire population, hence, the correct interpretation is:
- P(Y< 16) = 0.041. About 4.1% of all toco toucans weigh less than 16 ounces

Have a blessed day 
 
        
                    
             
        
        
        
4inches = 1/3 of a foot (4inches x 3 = 12 inches) - so she can cut 3 out of each foot
1 yard = 3 feet - so she can cut 3 x 3 = 9 out of each yard
18 x 9 = 162 pieces
