Question:
Suppose that a commercial bakery produces chocolate chip cookies. Based on extensive testing, the bakery has determined that the ideal number of chocolate chips per cookie is 18.1n the past, master bakers mixed the dough and spooned it onto sheet pans by hand, but the owners have decided to test a new machine.
The machine extrudes dough onto baking sheets at a uniform rate. It runs continuously from 6:00 a.m. until 2:00 p.m. The number of chips per cookie depends on the viscosity of the dough, and because the dough stiffens as it sits in the machine, the machine produces cookies that contain the optimal number of chips. 18 per cookie, between the hours of 6:30 am, and 11 a.m. The distribution of cookies is shown in the graph below.
Compute the proportion of cookies produced each day that contain the optimal number of chocolate chips. Scroll a percentage with one decimal of precision. ______%.
