. A researcher took a random sample of 600 college students andsurveyed them about how many days of class they missed persemester. On average, the sample missed 3.1 days of class. If thesample standard deviation is .45, construct a confidence intervalto estimate the true population mean at the 95% confidence level(.05 alpha level). Make sure to interpret your results in asentence or two! (HINT: Make sure you use the correct formula forthis question, keep in mind that you do not know the populationstandard deviation.)
