Aresearcher claims that 90% of people trust dna testing. in a survey of 100 people, 91 of them said that they trusted dna testing. is the actual proportion of people who trust dna testing larger than 90%? test the researcher’s claim at the 1% level of significance.

You must know that % is a number out of 100.

Therefore given 91/100 trusted DNA surveying, we know as a percentage this is 91% from the equation below:

(91/100)*100=91

We can conclude that 1%=1 person.

Although the difference is only 1 (91-90=1), the actual proportion of people who trust DNA testing is larger than the 90% by 1%.
