National statistics show that 23% of men smoke and 18.5% of women smoke. A random sample of 180 men

b.) Perform the appropriate confidence interval for the data in part 6. Don't forget to make a concluding

statement.

c.) Does the confidence interval that you found in part b confirm the results of part a? Explain why or why

not.
