A statistics tutor wants to assess whether her remedial tutoring has been effective for her five students. She decides to conduc
Snezhnost [94]

Answer:

The test statistic value is, <em>t</em> = -5.245.

The effect size using estimated Cohen's d is 2.35.

Step-by-step explanation:

A paired <em>t</em>-test would be used to determine whether the remedial tutoring has been effective for the statistics tutor's five students.

The hypothesis can be defined as follows:

<em>H</em>₀: The remedial tutoring has not been effective, i.e. <em>d</em> = 0.

<em>Hₐ</em>: The remedial tutoring has been effective, i.e. <em>d</em> > 0.

Use Excel to perform the Paired <em>t</em> test.

Go to Data → Data Analysis → t-test: Paired Two Sample Means

A dialog box will open.

Select the values of the variables accordingly.

The Excel output is attached below.

The test statistic value is, <em>t</em> = -5.245.

Compute the effect size using estimated Cohen's d as follows:

\text{Cohen's d}=\frac{Mean_{d}}{SD_{d}}

                =\frac{0.54}{0.23022}\\\\=2.34558\\\\\approx 2.35

Thus, the effect size using estimated Cohen's d is 2.35.

The figure is a parallelogram.
slavikrds [6]
Answer:  " m∠ACD = 40° " .
______________________________________________________
Explanation:
______________________________________________________
We are asked to find:  "m∠ACD" ; 
______________________________________
Note:  m∠ACD  =  m∠ABD ; 
______________________________________________________
So, given: 

m∠ACD  =  (4x + 4)° ;

m∠ABD =   <span>(6x - 14)° ;
_______________________________________________________
  4x + 4 = 6x - 14 ;

Solve for "x" ; then solve for:  "m</span>∠ACD"  ;
_______________________________________________________
 Add "14" to each side of the equation; and subtract "4x" from each side of the equation ; 

  4x + 4 + 14 - 4x  = 6x - 14 + 14 - 4x  ;

to get:

18 = 2x ;

↔  2x = 18 ;

Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; & to solve for "x" ;
__________________________________________________________
     2x / 2 = 18/2 ;

      x = 9 .
_________________________________________________________
Now, to solve for:  " m<span>∠ACD "  :
</span>_________________________________________________________
      m∠ACD =  <span>(4x + 4)°  ;

Substitute "9" for "x" ; 
</span>
      m∠ACD = (4*9) + 4 = 36 + 4 = 40° .
_____________________________________________
Answer:  " m∠ACD = 40° " .
_____________________________________________
Let us check our answer:
_____________________________________________
m∠ACD = 40 ; and m<span>∠ABD = (6x - 14) ;

</span>m∠ACD = ∠ABD ; 
<span>
Since </span>m∠ABD = (6x - 14) ;  

If x = 9;  if we plug in "9" into the expression for "m∠ABD" ; will the value obtained be "40" ??

m∠ABD = (6x - 14) ;  Let us plug in "9" for "x" ; to see if the value obtained is "40"

6x - 14 = ? (6*9) - 14 ??
 
6x - 14 = ?  54 - 14 ??

6x - 14 = ? 40 ?? Yes!
