Question

A Test of Independence is performed to determine if there is an association between gender and grades at the significant level of αα = 0.01. The following table summarize the final grade of students in a classs during a particular semester. Round expected values to one decimal place.

grade	A (Observed)	A (Expected Value)	B (Observed)	B (Expected Value)	C (Observed)	C (Expected Value)	Row Total
Male	5		14		12		31
Female	7		10		11		28
Column Total	12		24		23		59

H: Hypotheses

Ho:Ho:Select an answer gender Males Females A and Select an answer grade Males Females B are Select an answer independent dependent

Ha:Ha:Select an answer gender Males Females A and Select an answer grade Males Females B are Select an answer independent dependent

Original Claim: Select an answer H₀ H₁

Enter the critical values, along with the significance level and degrees of freedom χ2χ2_(αα,df) below the graph. (Graph is for illustration only. No need to shade.)

X2Χ2_( ,) =

Test Statistic χ2χ2 =  (Round to three decimal places.)

P-value =  (Round to four decimal places.)

Decision: Select an answer reject H₀ fail to reject H₀ accept H₀ reject Hₐ fail to reject Hₐ  .

Conclusion:

There Select an answer is is not significant evidence to conclude that Select an answer gender Males Females A and Select an answer grade Males Females B are Select an answer independent dependent .
