For each situation, state the null and alternative hypotheses: (Type "mu" for the symbol μ , e.g. mu > 1 for the mean is greater than 1, mu < 1 for the mean is less than 1, mu not = 1 for the mean is not equal to 1. Please do not include units such as "mm" or "$" in your answer.)
(a) The diameter of a spindle in a small motor is supposed to be
4.8 millimeters (mm) with a standard deviation of 0.12 mm. If the
spindle is either too small or too large, the motor will not work
properly. The manufacturer measures the diameter in a sample of 52
spindles to determine whether the mean diameter has moved away from
the required measurement. Suppose the sample has an average
diameter of 4.74 mm.

(b) Harry thinks that prices in Caldwell, Idaho, are lower than
the rest of the country. He reads that the nationwide average price
of a certain brand of laundry detergent is $16.85 with standard
deviation $1.19. He takes a sample from 48 local Caldwell stores
and finds the average price for this same brand of detergent is
$17.57.
