Question

1. The US Centers for Disease Control conducts the National Youth Tobacco Survey each year. The preliminary results from 2019 show that e-cigarette use is up among US teens while cigarette use is down. In the sample of 1582 teens, 92 reported smoking a cigarette in the last 30 days. (a) Give notation and define the parameter we are estimating. (b) Give notation and value of the sample statistic. (c) Verify that the conditions are met. (d) Find the standard error for this estimate. Use the appropriate formula. (e) What is $z^$ for a 99% confidence interval? Use R and include your code and output. (f) What is the 99% confidence interval? Use the formula involving $z^$. (g) Interpret the CI in context. Use a complete sentence. (h) What is the best estimate for the parameter we are estimating? (i) What is the margin of error?
