Out of a sample of 200 students, 100 indicated that they preferred chocolate ice cream to vanilla ice cream.

a.Estimate the value of the population proportion of those who preferred chocolate ice cream.(Round the final answer to 3 decimal places.)

Estimated population proportion

b.Compute the standard error of the proportion.(Round the final answer to 4 decimal places.)

Standard error of the proportion

c.Determine a 80% confidence interval for the population proportion of those who preferred chocolate ice cream.(Round the final answers to 3 decimal places.)

Confidence interval for the population proportion is betweenand.

d.Interpret your findings.

If 200 such intervals were determined, the population(Click to select)? (mean/proportion)would be included in aboutintervals.
