Question
Seventy five (75) randomly selected chemistry graduates with doctoral degrees have
a mean starting weekly salary of RM 1355 with a standard deviation of RM 216, and
90 randomly selected physics graduates with the doctoral degrees have a mean
starting weekly salary of RM 1620 with a standard deviation of RM 241. Do the data
suggest, at the 10% level, that there is a significant difference in mean salaries for
the chemistry graduates and physics graduates with doctoral degrees?
