The weights, in pounds, of the cats in an animal adoption center are normally distributed. If a random sample of cats is taken and the confidence interval is (7.9,12.7), what is the margin of error

Answers

Answer: 2.4

Step-by-step explanation:

Given : The weights, in pounds, of the cats in an animal adoption center are normally distributed.

The confidence interval is (7.9,12.7) (1)

Let $\overline{x}$ be the sample mean of the weights, in pounds, of the cats in an animal adoption center.

We know that the confidence interval for population mean is given by :-

$(\overline{x}-E,\overline{x}+E)$ (2)

From (1) and (2)

$\overline{x}-E=7.9-------(3)\n\n\overline{x}+E=12.7--------------(4)$

Subtracting (3) from (4), we get

$2E=4.8\n\n\Rightarrow\ E=2.4$

Hence, the margin of error is E = 2.4

Given the age in years, t, of a water-transport pipe, the formula R = 17 + 4 t can be used to predict the rate of water leakage (in gallons per minute) from the pipe as it carries water from the headquarters of a farming cooperative to farmland a mile away. What is the meaning of the constant 17 in the function R ?A. Initially the pipe leaks at 4 gallons per year.
B. Initially the pipe leaks at 17 gallons per year.
C. Initially the pipe leaks 17 gallons.
D. Initially the pipe leaks at 4 gallons per minute.
E. Initially the pipe leaks 4 gallons.
F. Initially the pipe leaks at 17 gallons per minute.

Answers

Answer: F. Initially the pipe leaks at 17 gallons per minute.

Step-by-step explanation:

Given the equation below:

R = 17 + 4t

Where R is the rate of leakage in gallons per minute,

And t is the age of pipe in years.

The rate of leakage at time t = 0 ( initial rate of leakage )

R(0)= 17 + 4(0)

R(0)= 17 gallons per minute.

Therefore the initial rate of leakage is 17gallons per minute

Final answer:

The constant 17 in the function R = 17 + 4t represents the initial rate of water leakage from the pipe when it is brand new. The correct answer is option C. Initially the pipe leaks 17 gallons.

Explanation:

The constant 17 in the function R = 17 + 4t represents the initial rate of water leakage from the pipe when it is brand new. This means that option C. Initially the pipe leaks 17 gallons is the correct answer.
