Answer:
23% of people who prefer plan I are from the 36–45 age group, and 42% of people from the 46–55 age group prefer plan II.
Step-by-step explanation:
___________Plan I___ Plan II ___Neither
Ages 26–35__ 19_____ 14_______ 17
Ages 36–45__ 14 _____28_______ 8
Ages 46–55__ 27 _____21_______ 2
Total Number who prefer plan 1 = (19 + 14 + 27) = 60
Number in the 36 - 45 age group = 14
Percentage = 14 / 60 = 0.2333 = 23%
Number of people in the 46-55 age group = (27 + 21 + 2) = 50
Number on the age group who prefer plan II = 21
Percentage = 21 / 50 = 0.42 = 0.42 * 100 = 42%
