Find out the drift speed of the electrons in the wire
An aluminum wire carrying a current of 4.0A has a cross-sectional area of9.010-6m2. Find the drift speed of the electrons in the wire. The density of aluminum is 2.7 g/cm3. (Assume three electrons are supplied by each atom.)

A manufacturer of strapping tape claims that the tape has a mean breaking strength of 500 psi. Experience has shown that breaking strengths are approximately normally distributed, with a standard deviation of 48 psi.
The manufacturer wants to check that the mean length of their bolts is 160 mm, and so takes a sample of 50 bolts and uses a one tail test with ? = .01 (i.e. H0: µ ? 160). What is the probability of a type II error if the actual mean length i
