Question

Four hundred people were asked whether gun laws should be more stringent. three hundred said "yes," and 100 said "no." the point estimate of the proportion in the population who will respond "no" is
a. 75
b. 0.75
c. 0.5
d. 0.25

Answer 1

To find relative frequency of no voters; 

p(A)=favourable outcomes/total outcomes 

p(A)=100/400 

= 1/4 or 0.25 

Therefore, the probability a person will respond with a no is 0.25.

Hope I helped :)
