Let 'p' be the new proportion of high school seniors who felt that "getting rich" was an important personal goal .
Claim : 
We know that the null hypothesis has equal sign.
Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-
And the alternative hypothesis must be :-
Hence, the null hypothesis and the alternative hypothesis that we would use for this test :
With this problem, it's essentially asking how many groups of 6 can fit into 324. We can do that simply by dividing 324 by 6 to get 54.

Step-by-step explanation:
The amplitude is the maximum distance away from the middle of the wave. Here we can see that the middle of the wave is the x axis and the farthest point (largest difference between the y coordinate of the x-axis, or the line y = 0, and the wave) is 1 unit away.
2n-4= n-10
-n. -n
n-4=-10
+4. +4
n=-6
Final answer: -6
A=$20.20/10gal=$2.02 per gal
B=$26.04/12gal=$2.17 per gal
C=$28.14/14gal=$2.01 per gal
D=$30.45/15gal=$2.03 per gal
So C is the cheapest per gallon.
