Find the margin of error E at 95 confidence level and conclu
Find the margin of error (E) at 95% confidence level and conclude the confidence interval used to estimate the population proportion of the following binomial distribution. When a simple random sample of size n = 168 was taken from the citizens of Ottawa to check if their Blood Rh is positive and x = 96 was the number of successes.
E = 0.0748, Confidence interval = 0.5714 +/- 0.0748
E= 0.00286, Confidence interval = 0.5714 +/- 0.00286
E= 0.1310; Confidence interval = 0.5714 +/- 0.1310
E= 0.0673, Confidence interval = 0.5714 +/- 0.0673
Solution
E= 0.00286, Confidence interval = 0.5714 +/- 0.00286
