Show all work. No work = no credit. The only exceptions to this are values obtained using 1-Var stats or LinReg(ax+b) or critical values from the t-table. If using normalcdf or tcdf, show all inputs. Show formulas where appropriate (outlier boundaries, margins of error, bounds of confidence intervals, test statistic). Round test statistics to 2 decimal places and p-values to 4 decimal places. Note: - Part (f) should refer to the result of part (e), not part (b). - In the hypothesis test, use alpha = .05.
