Question

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 148 with 83.8% successes at a confidence level of 90%. M.E. = [%] Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. Round final answer to one decimal place

Step 1

First, we need to find the critical value for a 90% confidence level. We can use a standard normal distribution table or a calculator to find this value. Using a calculator, we can use the formula: invNorm(1-(1-0.9)/2) = 1.645 (rounded to 3 decimal places). Show more…
