A researcher is studying drug use amongst teens. Based on her sample of 914 teens, the average drug use score 1.27, with a standard deviation of 0.80 (higher scores indicate more drug use).

A. Calculate the standard error of the mean. Round to the nearest hundredth (e.g. 0.12)

B. Next, construct the 95% confidence interval for the true average drug score in the population. Round to the nearest hundredth (e.g. 1.23). Submit answer in this format (x.xx to x.xx)
