Here, we are required to compare the density of different liquids with the same volume
Since density is the ratio of mass to volume, different liquids for example, kerosene and water if they have the same volume, will have different masses.
This is due to the difference in their densities.
Therefore, according to the statement in the question above;
While comparing the density of Liquids with the same volume, the liquid with the greatest density is heavier(more quantity of matter per unit volume) while the liquid with the least density is lighter( less quantity of matter per unit volume).

Answer:
Two tailed test
Test statistic = 3.20
Pvalue = 0.001
H1 : p ≠ 0.91
Step-by-step explanation:
Given :
Test of p=0.91 vs p≠0.91
The use if not equal to ≠ sign in the null means we have a tow tailed test, which means a difference exists in the proportion which could be lesser or greater than the stated population proportion.
The test statistic :
This is the Z value from the table given = 3.20
The Pvalue = 0.001
Since Pvalue < α ;Reject H0
1) Find the percentage difference between 12% and 100%.
100-12= 88%
1a) Put the percentage in its decimal form.
88%/100= 0.88
2) Divide 17.60 by 0.88
17.60/0.88= 20
Therefore, the original price of the lamp is $20.
Hope this helps!
$60 x (100%+15%+7%) = $60 x 122% = $73.20
