Question

I know we are supposed to utilize the Central Limit Theorem due to the parameters given in the problem. I'm just not sure how to begin solving it.

2. A confidence interval is desired for the true average stray-load loss u (watts) for a
certain type of induction motor when the line current is held at 10 amps for a speed
of 1500 rpm, such motors are used for appliances such as table fans, ceiling fans,
and kitchen mixers. Assume that stray-load loss is normally distributed with with
= 3.0.
a. (Austin) Compute a 95% confidence interval for u when n =
100 and z = 58.3.
b. (Austin) Consider the following statement: There is a 95% chance that u is
between u and l, where u and l are obtained from part (a). Is this statement
correct? Why or why not?
