A random sample of museum visitors were asked whether they will purchase tickets to an upcoming exhibit. The resulting confidenc
e interval for the proportion of visitors who will purchase tickets is (0.1,0.2). What is the margin of error?
1 answer:
Answer:
the margin of error is 0.05
Step-by-step explanation:
Margin of error = confidence interval ÷ 2
MOE = CI ÷ 2
Confidence interval CI = 0.2 - 0.1 = 0.1
MOE = CI ÷ 2 = 0.1 ÷ 2 = 0.05
the margin of error is 0.05
