Opposed to death penalty. Year 2000- 801 opposed out of 2565. Year 1993 337 opposed out of 1488.
I have two samples, one is 31.2% and one is 22.6%. I am trying to calculate the 95% confidence interval in context of this situation. ALso i need the formula that is used to calculate the interval and substitute appropiate numerical values into the formula. Then with this how do i find the value of (P1 with a ^ over it-P2 with a ^ over the P)So with this how do I find the 90% confidence interval for the difference between the population proportions opposed to the death penalty in the years 2000 and 1993.
