Please use the regression to estimate the effectiveness
(estimate the value of y) if the advertisement expenses X=30,
and estimate the advertisement expenses level (estimate the
value of X , X ) for effectiveness y = 50. ......

Distribution Calculations

After sample data is entered in either Statistic (SD) or Regression
(REG) mode, you can perform the normal distribution or
probability distribution calculation such as P(t), Q(t) and R(t) in
which t is the variate of the probabilistic experiment.
