Given that 
the weight of football players is distributed with a mean of 200 pounds and a standard deviation of 25 pounds.
And we need to find What is the minimum weight of the middle 95% of the players?
Explanation - 
 Using the Empirical Rule, 95% of the distribution will fall within 2 times of the standard deviation from the mean.
Two standard deviations = 2 x 25 pounds = 50 pounds
So the minimum weight = 200 pounds - 50 pounds = 150 pounds
Hence the final answer is 150 pounds.
 
        
             
        
        
        
Answer:
SSbetween treatments
Step-by-step explanation:
SSbetween treatments or Sum of square between treatments is used to measure and compare the mean differences between treatments from which the variance will be computed. 
 
        
             
        
        
        
Answer:
Total length after 33 days will be 117 miles 
Step-by-step explanation:
A construction crew is lengthening a road. The road started with a length of 51 miles.
Average addition of the road is = 2 miles per day 
Let the number of days crew has worked are D and length of the road is L, then length of the road can represented by the equation 
L = 2D + 51
If the number of days worked by the crew is = 33 days 
Then total length of the road will be L = 2×33 + 51 
L = 66 + 51 
L = 117 miles
Total length of the road after 33 days of the construction will be 117 miles.
 
        
             
        
        
        
I think it’s 12
1/3 = 4/12
1/4 = 3/12 
Hope it’s correct
