0.4 % of total people had allergic reaction
Solution:
Given that company that makes hair-care products had 8000 people try a new shampoo
Of the 8000 people 32 had allergic reactions
To find: percent of the people had allergic reaction
From given information,
Total number of people = 8000
Number of people with allergic reactions = 32
percent of the people had allergic reaction is given as:
[tex]\text{ percent } =\frac{\text{ Number of people with allergic reactions }}{\text{ Total number of people }} \times 100[/tex]
[tex]\rightarrow \frac{32}{8000} \times 100\\\\\rightarrow \frac{32}{80} = 0.4[/tex]
Thus 0.4 % of total people had allergic reaction
