An independent testing agency was hired prior to the May 2009 election to study whether or not the work output is different for construction workers employed by the state and receiving prevailing wages versus construction workers in the private sector who are paid rates determined by the free market. A sample of 100 private sector workers reveals an average output of 74.3 parts per hour with a sample standard deviation of 16 parts per hour. A sample of 100 state workers reveals an average output of 69.7 parts per hour with a sample standard deviation of 18 parts per hour. Is there evidence of a difference in productivity at the 0.10 level of significance? [Assume that the unknown variances are equal].

Question
An independent testing agency was hired prior to the May 2009 election to
study whether or not the work output is different for construction workers employed by the state and receiving prevailing wages versus construction workers
in the private sector who are paid rates determined by the free market. A
sample of 100 private sector workers reveals an average output of 74.3 parts
per hour with a sample standard deviation of 16 parts per hour. A sample of
100 state workers reveals an average output of 69.7 parts per hour with a sample standard deviation of 18 parts per hour. Is there evidence of a difference
in productivity at the 0.10 level of significance? [Assume that the unknown
variances are equal].
