Observed Frequencies
Under 39 39 to 49 50 and over
Promoted 42 36 18
Not Promoted 78 44 40
9 What is the Expected Frequency for "Under 39" and "Not Promoted?"
10 What is the Expected Frequency for "50 and over" and "Promoted?"
11 What is the value for the Test Statistic?
12 What is the p-value for this Chi-square Test of Independence of "Promotion" and "Age?" Note, you will need to use the function: CHISQ.TEST.
13 Does the analysis show a statistically significant association between "age" and "promotion status?" Yes or No.
