Question 1 0/2 pts O 10 2 4 0 Det Suppose the true proportion of voters in the county who support a restaurant tax is 0.35. Consider the sampling distribution for the proportion of supporters with sample size n = 158. What is the mean of this distribution? What is the standard error (i.e. the standard deviation) of this sampling distribution, rounded to three decimal places?
