35,23,32,25,27,31,29,30
1st: Order data from smaller to greater: 23,25,27,29,30,31,32,35

2nd Find the median of the set (central value). Since the number of data is even, then the median is the average between 29 & 30 = (29+30)/2 =29.5,(we will not use the median value, just for indication)

3rd, Find the central value of the subset on the left of 29 (that is 23,25,27)
This lower median =25 . This is called Q1
4th , Do the same with the subset on the right of 30 (that is 31,32,35).
This higher median = 32 is called Q3 (for your info the 1st median=29.5 is Q2)
The IQR or inter quartile range is Q3 - Q1 (or upper - lower Q)
IQR = 32-25) =7

Factor this trinomial.

andrew11 [14]

Answer:

C

Step-by-step explanation:

If you were to factor the equation out you would get

(x-5x)(15-3)

Simplify it to

x(1-5) -3(-5-1)

Where you would then get

(x-3)(x-5)

Consider the following regression output where the dependent variable is testscores and the two explanatory variables are the st

jeyben [28]

Answer:

The correct option is (A).

Step-by-step explanation:

The multiple linear regression equation is given by, $y=\alpha +\beta _{1} x_{1}+\beta _{2}x_{2}$ , where <em>α</em> = constant and <em>β</em> $_{i}$ = slope coefficients of regression line.

To test if there is a important relationship amid <em>X</em> $_{i}$ and <em>Y</em>, we use the <em>t</em>-statistic test.

The <em>t</em>-statistic for regression coefficient analysis is given by,

$t=\frac{\beta_{i}}{S.E._{\beta_{i}}}$

The regression equation for test scores dependent upon the two explanatory variables, the student-teacher ratio and the percent of English learners is:

$\text{TestScore} = 698.9 - 1.10 \text{ STR} - 0.650 \text{ PctEL}$

A <em>t</em>-test for the significance of the regression coefficient of variable student-teacher ratio (STR) is conducted.

The test statistic is found to be, <em>t</em> = 2.56.

The regression coefficient of variable STR is, 1.10.

Compute the standard error of the regression coefficient as follows:

$t=\frac{\beta_{i}}{S.E._{\beta_{i}}}$

$S.E._{\beta_{i}}=\frac{\beta_{i}}{t}$

$=\frac{1.10}{2.56}\\\\=0.4296875\\\\\approx 0.43$

The standard error of the regression coefficient is 0.43.

Thus, the correct option is (A).
