A hypothetical study concerned with estimating th187e amount of marijuana use per year among a teenage population obtained a sample of ll0 high-school students. With the following sample statistics, construct a 95-confidence interval around the mean number of times this sample uses marijuana in a given 6-month period: Mean of the sample = 5.3; the standard deviation of the sample = 4.3 and the sample size = 110 What does the interval you constructed tell us about marijuana use in the population? Interpret these results.
