A hypothetical study concerned with estimating the amount of marijuana use per year among a teenage population obtained a sample of 125 high school students. The average number of times per year a student used marijuana was 4.7, with a standard deviation of 2.9. Construct a 99% confidence level, what is the LOWER bound for the confidence interval

Confidence interval 99%

Step-by-step explanation:

In this case, we have to estimate a confidence interval (CI) with an unknown standard deviation of the population (we only known the s.d. of the sample).

The estimated standard deviation is

For a 99% CI and degrees of freedom df=124, the t-statistic is t=2.616.

So the confidence interval is:

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
