Clark Heter is an industrial engineer at Lyons Products. He would like to determine
whether there are more units produced on the night shift than on the day shift. A sample of 56 day-shift workers showed that the mean number of units produced was 336.A sample of 61 night-shift workers showed that the
mean number of units produced was 341 with a population standard deviation of 25 units. At the .02 significance level, is the number of
units produced on the night shift larger?

units produced on the night shift larger?
1.this is a one or two tailed test?
2.the decision rule is to reject h0 if z<
(Negative amount should be indicated by a minus sign.Round your answer to 2 decimal
places
3.the test statistic is z=
4.what is your decision regarding h0?
Reject?do not reject?

Solution
1) THIS WILL BE A TWO TAILED TEST BECAUSE IN THIS WE HAVE TO COMPARE THE TWO DIFFERENT PROPORTION WITH SIGNIFIANCE OF 0.02.
HENCE THE ANSWER WILL BE TWO TAILED TEST.
