Problem: Choose a common fruit fly Drosophila melanogaster at random. Call the length of the thorax (where the wings and legs attach) Y. The random variable Y has the Normal distribution with mean μ= 0.800 millimeter (mm) and standard deviation μ= 0.078 mm. The probability P(Y > 1) that the fly you choose has a thorax more than 1 mm long is about
(a) 0.995.
(b) 0.5.
(c) 0.005. CH
A toaster uses a heating wire. When the toaster is turned on at22 °C, the initial current is 1.19 A. A few seconds later, thetoaster warms up and the current has a value of 0.927 A. The average temperature coefficient of resistivity for this wire ..
