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 145 with 39 successes at a confidence level of 90%. M.E. =_____ % (report answer accurate to one decimal place; answer should be reported as a percent, not a decimal—though do not type the percent sign) Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
