Answer:

Following are the solution to the given question:

Step-by-step explanation:

H_0: Management quality and corporate reputation are independent.  

H_1:  Management quality and corporate reputation are not independent.

Test statistic:

\to \chi^2 = \frac{\sum (O-E)^2}{E}

= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333    +0+3.2143+7.5\\\\= 17.02806

The critical \chi^2 fordf = (r-1)(c-1) = (3-1)(3-1)= 4 and \alpha = 0.05 is \chi^2= 9.4877

Test statistic:

17.02806 > 9.4877 therefore rejecting the null hypothesis H_0.

p-value= 0.001909

Interpretation:

There is no internal governance quality as well as the reputation of the organization.

Answer:

d. 2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

45a−25+7a=79

45a+−25+7a=79

(45a+7a)+(−25)=79(Combine Like Terms)

52a+−25=79

52a−25=79

Step 2: Add 25 to both sides.

52a−25+25=79+25

52a=104

Step 3: Divide both sides by 52.

52a

52

=

104
