Researchers want to survey the mass of American alligators in a certain region. They want to maximize the efficiency of this eff
Sonja [21]

An appropriate statistical test that can be used to evaluate the usefulness of this method is Linear regression with t-test for significance of slope.

For this research, they want to measure the lengths of alligators and use the already obtained data relating the lengths of captured and released alligators to their masses, to obtain the masses of alligators whose lengths have been measured.

So, in this research survey, the masses of the alligators is the dependent variable which depends on the lengths.

Basically, the researchers measure the length of an alligator and use the data to work out its mass.

So, an appropriate method to relate the two variables is to use regression analysis on the already obtained data, to obtain the linear relationship between mass of the alligators and their lengths. So that, just by putting on the measured lengths of the alligators surveyed into this expression, their corresponding masses would be immediately obtained.

But the correctness of this expression obtained will be checked by using t-test for the significance of the slope obtained in the linear regression.

So, the appropriate statistical test that can be used to evaluate the usefulness of this method is: Linear regression with t-test for significance of slope.

PLEASE ANSWER!! <br> The graph below have the same shape. what is the equation for the red graph?
Serga [27]

Answer:

C

Step-by-step explanation:

given a function f(x) then

f(x) + c ← denotes a vertical translation of f(x)

• If c > 0 then shift vertically up

• If c < 0 then shift vertically down

Here the vertex of f(x) is at the origin and the vertex of g(x) is (0, 3 ), that is 3 units vertically up

Hence g(x) = x² + 3 → C

The area of a rectangle is (25x2 − 9y2) square units. Determine the dimensions of the rectangle by factoring the area expression
8_murik_8 [283]

Answer:

(5x+3y) and (5x-3y)

Step-by-step explanation:

From the concept on difference between two squares;

a² - b² = (a+b)(a-b)

Therefore;

25x² - 9y² = (5x+3y) (5x-3y)

Therefore the dimensions of the square are (5x+3y) and (5x-3y)
