A study was done to compare the population percentage of those that identify as male and support gun control to those that identify as female and support gun control.  Is the population percentage for those that identify as male and support gun control higher, lower, or not significantly different than the percentage for those that identify as female and support gun control. Population 1:  People that identify as male. Population 2.  People that identify as female. Sample Proportion 1 = 0.612 Sample Proportion 2 = 0.824 Sample Proportion Difference =
