Answer:
The true average mileage of the Libra Using Null hypothesis is as ;
H0:μ≤26
(Ha):μ >26
Step-by-step explanation:
Given:
Libra, will average better than 26 miles per gallon in the city
To Find:
Average mileage of the Libra.
Solution:
This problem is related to the null hypothesis and alternate hypothesis.
i.e Null Hypothesis is the statement which is true and statement which contradictory is called alternate hypothesis.
<em>“reject H0” if the sample information favors the alternative hypothesis.
</em>
<em>“do not reject H0” / “decline to reject H0” if the sample information is insufficient to reject the null hypothesis</em>
So given that condition is libra will have average better than 26
So it will include 26 and above values .
i.e. True condition is called as null hypothesis (H0)
so true average will be greater than 26
So H0:μ≤26
And the Alternate hypothesis will be the contradictory to true condition
(Ha):μ >26 .
Answer:
0.5% error
Step-by-step explanation:
We can use the percentage error formula, which is
.
We know that the approximated value was 8.04, however it is actually 8cm, so we can substitute inside the equation.
