Answer:
Start: With = 74.8%, Without = 25.2%
End: With = 85%, Without = 15%
Step-by-step explanation:
For percentages, find the total population first. At the Start that would be 374 + 126, which is 500. You then divide the sample by the population then/ multiply by 100.
For those With for the Start it is (374/500) x 100 = 74.8, for those Without for the Start it is (126/500) x 100 = 25.2.
For the End the total population would be 136+24 = 160.
For those With it would be (136/160) x 100 = 85, and those Without would be (24/160) x 100 = 15.
