Introduced in 1973 as the Publica Starlet 40 Series, it wasn't sold in North America until 1981, and by 1984, it was replaced by the Corolla FX in Toyota's North American lineup. The Starlet saw a total of five generations throughout its production.Link to StatKey's interactive normal distribution: http://www.lock5stat.com/StatKey/theoretical_distribution/theoretical_distribution.html#normalExplore math with our beautiful, free online graphing calculator.
