Answer:
Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951
Step-by-step explanation:
The fraction of older Americans who were included in the study and suffered broken bones during the three-year period?
This fraction = (Number of older Americans who suffered broken bones recorded during the three year period of the study)/(Total number of older Americans involved in the study)
Number of older Americans who suffered broken bones recorded during the three year period of the study = (11 from those that took the additional supplements) + (26 from those that did not take additional supplements) = 11 + 26 = 37
Total number of older Americans involved in the study = 389
Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951
