inessss [21]

Answer: |p-72% |≤ 4%

Step-by-step explanation:

Let p be the population proportion.

The absolute inequality about p using an absolute value inequality.:

|p-\hat{p}| \leq E , where E = margin of error, \hat{p} = sample proportion

Given:  A poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% .

|p-72% |≤ 4%

⇒    72% - 4% ≤ p ≤ 72% +4%

⇒  68%  ≤ p ≤  76%.

i.e. p is most likely to be between 68% and 76% (.

scZoUnD [109]

Answer:

where L = length, W = width, H = height

The carrier is 20 inches long, 13 inches wide, and 16 inches high.

Therefore, its volume is:

V = 20 * 13 * 16\\V = 4160 in^3

The volume of the dog carrier is 4160 cubic inches.
