Ang . conbol. Total 125 sverian cancer age all age 50-54 40 43 Ни к ил Le и Scanned with Caccann attributes 85 92 135 - 12 +

Actual Values:
3 7
40 85

Expected ed Values:

3.18519 6.81482
39.8148 85.1852

Chi-Squared Values:
0.0107666 0.00503221
0.000861326 0.000402576

Chi-Square = 0.0170627

Degrees of Freedom = 1

p = 0.896073

Since p value is large we conclude that there is no significant association between early age and ovarian cancer
