(a) How many degrees of freedom are used Recall that there were 5 sources of fraud/identity theft and, of course, 2 genders. Approximate the P -value and conclude the test at the 5% level of significance. Would it seem that gender and source of fraud/identity theft are independent
(b) From this study, can Charlotte identify which source of fraud/identity theft is dependent with respect to gender Explain.
