Calculate the degrees of freedom dfn = nCollege - 1 Find tcrit We can do this by using R's qt function, which takes two arguments - - The first argument is the percentile you are looking for. So if you want the median value of distributed variable, you'd use .50. We want the .025th and the .975th (so that we get the 95% confidence interval). The second argument is the degrees of freedom, dfn. - Put them together: tcrit = qt(.975, dfn) Calculate the lower and upper bounds of the 95% confidence interval andprint them in your code chunk. Based on the 95% confidence interval, we can answer the question "is the population mean wage for college-educated workers equal to $1,200?" by testing the null hypothesis. Question: What is your answer to this question, in your own words, and why?
