In a regression analysis involving 30 observations, the following estimated regression equation was obtained. If required enter negative values as negative numbers. In a regression analysis involving 30 observations
Interpret b1, b2, b3, and b4 in this estimated regression equation (to 1 decimal). Assume that for each coefficient statement, the remaining three variables are held constant. Enter negative values as negative numbers.
b1 = estimated change in y per 1 unit change in x1
b2 = estimated change in y per 1 unit change in x2
b3 = estimated change in y per 1 unit change in x3
b4 = estimated change in y per 1 unit change in x4
Predict y when x1 = 10, x2 = 5, x3 = 1, and x4 = 2 (to 1 decimal).

In this, question the equation is missing that's why in the solution we define the equation and its complete solution:

Let the given equation:

units expect changes in the y for each 1 unit change in

units expect changes in the y for each 1 unit change in  

units expect changes in the y for each 1 unit change in

units expect changes in the y for each 1 unit change in

Calculating the estimated value of the y when:

Put the value into the above-given equation:

So, the final answer is "57.1".

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

the true ones are a b and d
