You intend to estimate a population proportion with a confidence
interval. The data suggests that the normal distribution is a
reasonable approximation for the binomial distribution in this
case.
While it is an uncommon confidence level, find the critical value
that corresponds to a confidence level of 81.2%.
(Report answer accurate to three decimal places with
appropriate rounding.)

solution
At 81.2%confidence level the z is ,
= 1 - 0.812 = 0.188
/ 2 = 0.188 / 2 = 0.094
Z/2 = Z0.094= ±1.317

Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 336 with 35.1% successes at a confidence level of 99.5%. M.E. = % Report answer accurate to one decimal place (as a number of percentage points). Answer should be obtained without any preliminary rounding (however, the critical value may be rounded to 3 decimal places).
