During the 1960s, when the Cold War was fueling an arms race between the Soviet Union and the United States, the number of American intercontinental ballistic missiles (ICBMs) rose from 18 to 1054 (9). Moreover, the sizes of the ICBM stockpile during that decade had an S-shaped pattern, suggesting that the logistic curve would provide a good model. Graph the following data, and approximate the xy-relationship with the function y = L/1+ea+bx. Assume that L = 1055.
