What is the approximate 95% prediction interval for the dependent variable when the independent variable value is 20, assuming t

he fitted regression line is: Y = 1.50 + 6.0(X). Assume the sample size is 20 and the standard error of the regression (SEE) is 1.2. You should use the "rule of thumb" used in class here.

Answer:

Step-by-step explanation:

95% prediction interval for the dependent variable when the independent variable value is 20,

assuming the fitted regression line is: Y = 1.50 + 6.0(X).

Assume the sample size is 20

Y = 1.50 + 6.0(X)

sample X = 20

here predicted value = 1.5+6*20

= 121.5

therefore 95% prediction interval for the dependent variable

the standard error of the regression (SEE) is 1.2.

=121.5 \pm 2*1.2\\\\=121.1+2*1.2\\\\=121.1+2.4\\\\=123.9\ \texttt {and} \\\\=121.1-2*1.2\\\\=121.1-2.4\\\\=119.1 \\\\(119.10 \ \text  {to}\ 123.90)

Graph the solution to this system of inequalities in the coordinate plane.
olga nikolaevna [1]

Answer:

Step-by-step explanation:

3y > 2x + 12

y>\frac{2}{3}x+4

This inequality will be represented by the a dotted line and solution area for the inequality will be shaded area (In red) above the dotted line.

2x + y ≤ -5

y ≤ -2x - 5

This inequality will be represented by a solid line and solution area will be the shaded area (in blue) below the solid line.

Therefore, common area of both will be the solution area for the system of inequalities.

Help me please I literally don’t understand any of this. I know it’s easy too.
Ber [7]

Holigina, this is the solution:

Let's recall that √x = x ^(1/2)

Therefore,

√x√x = x ^(1/2 + 1/2) = x^1 (We sum the exponents of the same base)

The correct answer is C. 1
