5.  Female Cashiers and Servers Labor statistics indicate that 77% of cashiers and servers are women. A random sample of cashiers and servers in a large metropolitan area found that 112 of 150 cashiers and 150 of 200 servers were women. At the 0.05 level of significance, is there sufficient evidence to conclude that a difference exists between the proportion of servers and the proportion of cashiers who are women?
