Age 16-24 25-34 35-44 45-54 55-64 65-74 75-84 85 and older 104 Gender Male 79 65 59 36 25 18 Female 41 29 29 27 23 20 10 11 Click the icon to view additional information regarding the homogeneity of proportions test. Are the proportions the same for each group? O A. Yes, the value of x is high enough to conclude the proportions are the same. O B. No, the value of y is too low to conclude the proportions are the same. OC. Yes, the value of x is low enough to conclude the proportions are the same. O D. No, the value of y is too high to conclude the proportions are the same.
