Answer:  The number of first-year residents she must survey to be 95% confident= 263
Step-by-step explanation:
When population standard deviation ( )  is known and margin of error(E) is given, then the minimum sample size (n) is given by :-
)  is known and margin of error(E) is given, then the minimum sample size (n) is given by :-
 , z* = Two-tailed critical value for the given confidence interval.
, z* = Two-tailed critical value for the given confidence interval.
For 95% confidence level , z* = 1.96 
As,  = 8.265, E = 1
 = 8.265, E = 1
So, ![n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}]](https://tex.z-dn.net/?f=n%3D%20%28%5Cdfrac%7B1.96%5Ctimes8.265%7D%7B1%7D%29%5E2%20%3D%2816.1994%29%5E2%5C%5C%5C%5C%3D%20262.42056036%5Capprox263%5C%20%5C%20%5C%20%5B%5Ctext%7BRounded%20to%20the%20next%20integer%7D%5D)
Hence, the number of first-year residents she must survey to be 95% confident= 263
 
        
             
        
        
        
Answer:
<h2>
A</h2>
Step-by-step explanation:
gradient = (-3+2)/(0-3)
gradient = 1/3
slope intercept form : y = mx + b
 m is the gradient which we have found to be 1/3
b is the y intercept that can either be -2 or - 3 (both the y coordinates)
therefore the equation would be y = 1/3 x - 3    (A)
