You want to estimate the average difference in the number of complaints filed by women at work and the number of complaints filed by men at work.  You took an SRS of 7 businesses and collected the following data for number of complaints in a year: men 1 3 2 4 6 3 5 women 8 7 6 3 5 12 15   Create a 90% confidence interval for the average difference in the number of complaints filed by women at work and the number of complaints filed by men at work (in a year).  You must do this using table C.  If this is a 2 sample interval, be sure to specify who is population 1 and who is population 2.  If this is a matched pairs interval, be sure to state the order you subtracted your data.  Once you create your interval, give a sentence explaining the meaning of the interval (what the numbers in the interval mean, NOT the meaning of 95%) in context of this problem.  Round to any appropriate number of decimals.
