(a) Find the mean for this sample and explain what it represents.
(b) Find the standard deviation for this sample.
(c) Find the median for this sample.
(d) The manager wishes to be able to finish at least 75% of the houses he contracts to build
within two weeks. Each of his workers works 40 hours a week. If the manager asks you to
determine the number of workers, how many workers he should hire? (Hint: The data are
not assumed to be bell shaped. Based on the Tchebysheff Theorem, interval ( ks, + ks)
contains at least (I Į k)% of the data.)
