A recent poll taken by the national ice cream industry shows that 32% of the population names vanilla as its favorite ice cream flavor. A sample of 200 people shows that only 20% of those polled names vanilla as their favorite ice cream flavor.To determine whether this sample supports the population proportion of 0.32, a simulation of 100 trials is run, each with a sample size of 50 and a point estimate of 0.20. The minimum sample proportion from the simulation is 0.16, and the maximum sample proportion from the simulation is 0.28.What is the margin of error of the population proportion using half the range?
Accepted Solution
A:
Hence margin of error for population proportion is option c which is 0.6 What is margin of error ?MoE refers to estimated point value that tells us how much difference is there from actual value.How to calculate?critical value * SD of populationGiven max sample proportion =0.28 and min sample proportion=0.16Hence we can directly calculate MOE by subtracting both = 0.28=0.16=0.6which is option no. cHence option c is 0.6 which is correct.learn more about margin of error
