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: 33 groups
Step-by-step explanation:
Number of people that signed for help = 130 people
Number of people that can join a group = 4.
Number of groups that will be formed will be:
= Number of people that signed for help / Number of people that can join a group
= 130/4
= 32.5
= 33 groups
Since there'll be a remainder of 2 people, they will form a new group making 33 groups.
<em><u>show the total cost for the first 4 months of this cellphone plan
:</u></em>
m 1 2 3 4
C ( $ ) 70 115 160 205
<em><u>Solution:</u></em>
Given that,
The equation is:
C = 45m + 25
Where,
C is the total cost in dollars
m is number of months
<em><u>show the total cost for the first 4 months of this cellphone plan
</u></em>
<em><u>First month</u></em>
m = 1
C = 45(1) + 25
C = 45 + 25
C = 70
<em><u>Second month</u></em>
m = 2
C = 45(2) + 25
C = 90 + 25
C = 115
<em><u>Third month</u></em>
m = 3
C = 45(3) + 25
C = 160
<em><u>Fourth month</u></em>
m = 4
C = 45(4) + 25
C = 205
<em><u>Thus the table is:</u></em>
m 1 2 3 4
C ( $ ) 70 115 160 205
Thus the table is formed
