Recently, a Montana Newspaper Asked People to Go to Their

Recently, a Montana newspaper asked people to go to their website and respond yes or no to the question: "Should federal protections on grizzly bears be lifted?" Of 933 opinions, 58.1% said "Yes", and 41.9% said either "No"
Or "Uncertain". Is it valid to conclude from the poll that over half of all Montana residents favor lifting the protections?

A) Yes, because 58.1% is far enough above 50% to conclude that the true proportion is more than one-half.
B) Yes, because the sample size is large enough to represent all 75,000 Montana residents.
C) No, because the sample is not likely to be representative of the population.
D) No, because the sample is too small given the population of 75,000 Montana residents.
