Suppose that you are interested in examining if it is true that on average men earn more than $30.00 a day more than women in a certain entry level positions in some technical fields. If sample data show that 80 men earned on average $353.78 a day with a standard deviation of $18.03, while 80 women earned on average $315.14 a day with a standard deviation of $21.22 per a standard deviation of $21.33, conduct a hypothesis test at the .01 level of significance.
