I believe that the population proportion of Elementary students in Texas who ride the bus to school is more than the population proportion of Elementary students in Oklahoma. In two independent polls I found that 659 of 3502 students ride the bus in Texas and 476 of 3201 students in Oklahoma ride the bus to school. Assume a random sample. Calculate a 90% confidence interval of the two proportions.

I believe that the proportion of individuals in Chicago that are vegan is less than those in New York. I found it hard find actual poll numbers on this so I will propose a fictional case: in a poll 60 of 315 adults living in Chicago are vegan, in New York 109 of 200 are vegan. I am 97% confident there are more Vegans in New York.
