Indicate the type of errors committed in the following cases:

i):  A driver is punished for no fault at him.                             
ii): A bad player is allowed to play a match.                              
iii): A poor student is promoted to the next class.                          
iv): `H_0: µ=500, H_1: µ ≠ 500. H_0`  is rejected while `H_0` is true.  
v): `H_0: µ=500, H_1: µ < 500. H_0`  is accepted while `H_0` is false.  

Solution:

i):  A driver is punished for no fault at him.                                             (Type 1 error)

ii): A bad player is allowed to play a match.                                             (Type 2 error)

iii): A poor student is promoted to the next class.                                       (Type 2 error)

iv): `H_0: µ=500, H_1: µ ≠ 500. H_0  `is rejected while `H_0 `is true.          (Type 1 error)

v): `H_0: µ=500, H_1: µ < 500. H_0`  is accepted while `H_0` is false.         (Type 2 error)
