(f) [6 pts] For each continuous variable, compute the 95% confidence interval for a population mean. (g) [6 pts] For each continuous variable, compute the 95% confidence interval for a population variance. (h) [6 pts] For each continuous variable, perform a statistical test to see whether its population mean is zero or not. (i) [10 pts] For each categorical variable, perform a t-test(thatx is, test whether there is significant mean difference pbetween two levels of each categorical variable) (j) [5 pts] Calculate correlations between continuous variables. (k) [5 pts]Perform a statisticalest to see whether the correlation between two continuous variables is significant or not. (1) [10 pts] Test independence between categorical variables. (m) [10 ptsFit a simple linear regression modelbating x to x1 (that is, X2 is a response variable) Write down the fitted model, and interpret
