The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 45 ounces and a standard deviation of 4 ounces. Use the Standard Deviation Rule, also known as the Empirical Rule. Suggestion: sketch the distribution in order to answer these questions. a) 68% of the widget weights lie between  oz and  oz b) What percentage of the widget weights lie between 37 and 49 ounces?  % c) What percentage of the widget weights lie above 33 ?  %
