problem_activity: Task
Each student in a random sample of students at a local high school was categorized according to gender (male or female) and whether they supported a proposal to increase the length of the school day by 30 minutes (oppose, support, no opinion). The following table summarizes the data for this sample.
|        |        | Opinion on Proposal to Increase Length of School Day |         |            |       |
|--------|--------|------------------------------------------------------|---------|------------|-------|
|        |        |                        Oppose                        | Support | No Opinion | Total |
| Gender |  Male  |                          50                          |   40    |     20     |  110  |
|        | Female |                          40                          |   40    |     10     |  90   |
|        | Total  |                          90                          |   80    |     30     |  200  |
What proportion of the students in this sample are male?
What proportion of the students in this sample support the proposal?
What proportion of the males in this sample support the proposal?
What proportion of the students in this sample who support this proposal are male?
