Question:

Assume that the readings on the thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A thermometer is randomly selected and tested. In each case, draw a sketch, and find the temperature reading corresponding to the given information.
In a manufacturing plant that makes boxes, the width of a certain type of box is normally distributed. The probability that the width is less than 23.9708 cm is 0.0721 and the probability that the width is more than 24.0404 cm is 0.0217. Find the mean and standard deviation of the box width.
