Suppose that 20% of the residents in a certain state support an increase in the property tax. an opinion poll will randomly sample 400 state residents and will then compute the proportion in the sample that support a property tax increase. how likely is the resulting sample proportion, ^p, to be within 0.04 of the true proportion, p (i. e., between 0.16 and 0.: use the sampling distribution of the sample proportion in this case.)
a)it is certain that the resulting sample proportion will be within 0.04 of the true proportion.
b)there is roughly a 99.7% chance that the resulting sample proportion will be within 0.04 of the true proportion.
c)there is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.
d)there is roughly a 68% chance that the resulting sample proportion will be within 0.04 of the true proportion.
