Doubt about a stata question

[Javiera Pavisic]

Hi there! I have a homework and I don't know how to solve this question. I have to calculate the percentage of people who have private insurance over the total (private insurance + public insurance) by quintiles and by age group. I have the variable "isapre" which is a dummy that takes the value 1 if the person has private insurance and 0 if not. I have the variable "quintiles" that I obtained from the xtile function from the variable "ypc_1", and four age groups: under 18 years old (minor_18), between 18 and 39 (between18_39), between 40 and 64 (between40_60) and over 65 (greater_65 ). I have the following stata output that I need to get to but I can't find the command. Could someone tell me how to get this command?

I'm sorry, but it is a policy of this Forum that we do not provide homework help. For that you should turn to your instructor, a teaching assistant, or perhaps your fellow-students depending on the rules and policies of your school. To be clear, advice for students working on dissertations and research projects is readily available here--but not homework help.
