Answer:
Since the null hypothesis is true, finding the significance is a type I error.
The probability of the year I error = level of significance = 0.05.
so, the number of tests that will be incorrectly found significant is computed as follow: 0.05 * 100 = 5
Therefore, 5 tests will be incorrectly found significant given that the null hypothesis is true.

Answer:
The slope is zero
Step-by-step explanation:
We can find the slope of a line given two points by using

  = (0-0)/(10-5)
  = 0/5
  =0
 
        
             
        
        
        
Pretty sure it would be 21x^2+16x+17y
