Claim: The majority of adults like pizza.
A sample of 400 randomly selected adults shows that 220 of them like pizza.
Based on the given sample information, do you think that the above claim is true? Why or why not?

JJ,
I tend to think it is true since 220/400 is more than 50% and it was a random sample. If a sample is truly random that we can consider it to be representative of the population.
If they had asked people coming out of a pizza shop, then I would say no.
