Answer:
B. The mean amount of  emitted by the new fuel is actually lower than 89 kg but they fall to conclude it is lower than 89 kg
 emitted by the new fuel is actually lower than 89 kg but they fall to conclude it is lower than 89 kg
Step-by-step explanation:
A Type II error is the failure to reject a false null hypothesis.
Given the null and alternate hypothesis of a fuel company which wants to test a new type of gasoline designed to have lower  emissions.:
 emissions.:

where  is the mean amount of
 is the mean amount of  emitted by burning one gallon of this new gasoline.
 emitted by burning one gallon of this new gasoline.
If the null hypothesis is false, then:

A rejection of the alternate hypothesis above will be a Type II error.
Therefore:
The Type II error is: (B) The mean amount of  emitted by the new fuel is actually lower than 89 kg but they fall to conclude it is lower than 89 kg.
  emitted by the new fuel is actually lower than 89 kg but they fall to conclude it is lower than 89 kg.

Answer:
152 degrees
Step-by-step explanation:
we know that
Exterior angle is supplementary to interior angle. Their sum is equal to 180 degrees
