Answer:
Im sorry but I am not really sure myself ! I hope you find or found your answer already !
Step-by-step explanation:
First you have to know the price of item.
EX: Say a candy car costs $1.50.

$1.50 x 30/100 = $.45
The item will decrease $.45.
$1.50 - $.45 = $1.05
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
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.:

where
is the mean amount of
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.
