Answer:
a.) The classes are successful
b.) The classes might not be successful.
c.) Type 11 error
d.) Yes
E.) No
Step-by-step explanation:
C.)
This means that we failed to reject H0 when it is actually FALSE and in fact the classes are successful , that means mean μ > 100, that is: null hypothesis is False.
D.)
Type 1 error occurs when we incorrectly reject H0 ; that is we rejected H0, when it is true
Here, H0, means the classes aren't successful, hence, incorrectly rejecting H0 means we have committed a type 1 error
E.)
Type 11 error means failing to reject H0
;
Here, H0, means the classes aren't successful,
Hence, if we fail to reject H0 in this scenario, we are right, hence, there is no possibility of making a type 11 error in this scenario
