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.
Explanation:
i. Calculating the percentage of people preferring plan I are from the 36–45 age group.
First, we need to get the number of that preferred plan 1.
Looking through plan 1 column.
Total = 19 + 14 + 27
Then we write out the number of people in the 36 - 45 age group that prefer plan 1
Number of 36 - 45 aged people that prefer plan I is 14.
Their percentage is then calculated as follows:
Percentage = (14 ÷ 60) * 100%
Percentage = 0.2333 * 100%
Percentage = 23.33%
Percentage = 23% (Approximated)
ii. Calculating the percentage of people from the 46–55 age group prefer plan II?
First we need to get the total of people from age group 46 - 55.
Total = 27 + 21 + 2 = 50
Then we write out those from this age group that prefer plan II
Tgese category of people are 21
Their percentage is then calculated as follows:
Percentage = (21 ÷ 50) * 100%
Percentage = 0.42 * 100%
Percentage = 42%
From option A through E, only option A satisfied the calculation above
