To start, letâs measure voltage on a AA battery: Plug the black probe into COM and the red probe into mAVÎ©. Set the multimeter to â2Vâ in the DC (direct current) range. Almost all portable electronics use direct current), not alternating current. Connect the black probe to the batteryâs ground or â-â and the red probe to power or â+â.
First, assume adult male heights are normally distributed with mean 70 inches and standard deviation 3 inches. Assume also that adult female heights are normally distributed with mean 64 inches and standard deviation 3 inches.irst, assume adult male heights are normally distributed with mean 70 inches and standard deviation 3 inches.

You and your friends have just measured the heights of your dogs (in millimeters): The heights (at the shoulders) are: 600mm, 470mm, 170mm, 430mm and 300mm. Find out the Mean, the Variance, and the Standard Deviation. Your first step is to find the Mean: Mean = 600 + 470 + 170 + 430 + 3005 = 19705 = 394.
