The ratio of dogs to cats at a local animal shelter is 13/25. Which statement must be true?
1 answer:
<em>Option:</em>
<em>a. for every 13 dogs, there are 25 cats. </em>
<em>b. there are twice as many cats as dogs at the shelter. </em>
<em>c. the shelter has more dogs than cats. </em>
<em>d. there are 25 animals in the shelter.</em>
Answer:
a. for every 13 dogs, there are 25 cats.
<em></em>

Represent Dogs with D and Cats with C;
So;
By comparison:
This implies that:
For every 13 D, there are 25 C
Hence: Option A is true

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.
