Smith is a weld inspector at a shipyard. He knows from keeping
track of good and substandard welds that for the afternoon shift 5%
of all welds done will be substandard. If Smith checks 300 of the
7500 welds completed that shift, what is the probability that he
will find between 10 and...

Answers to the following questions should be calculated in
Matlab and given to 4 decimal places. Be careful not to introduce
errors by rounding in any intermediate calculations as this may
lead to an incorrect final answer. A confidence interval is desired
for the true average load loss μ (watts) for a certain type of
induction motor when the line current is held at 10 amps for a
speed of 1500 rpm. A random sample of 52 motors were tested...
