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 supports a property tax increase. How likely is the resulting sample proportion to be within .04 of the true proportion (i. e., between .16 and .24)? (Hint: Use the sampling distribution of the sample proportion in this case.)
A. It is certain that the resulting sample proportion will be within .04 of the true proportion.
B. There is roughly a 99.7% chance that the resulting sample proportion will be within .04 of the true proportion.
C. There is roughly a 95% chance that the resulting sample proportion will be within .04 of the true proportion.
D. There is roughly a 68% chance that the resulting sample proportion will be within .04 of the true proportion.

1) your friend taylor missed class today and needs some identifying solutions of systems. explain to taylor where to find the solution(s) of any system using its graph 2)taylor graphs the following in desmos and decides that f(x) = g(x) at x = 0, x = 1, & x = 3. f(x) = 2x+1g(x) = 2x2+1 provide taylor some feedback that explains which part of the answer was incorrect and why.
