In a previous​ year, ​% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of females aged 15 and older and finds that are living alone. Is there sufficient evidence at the level of significance to conclude the proportion has​ changed?

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

1/800 is the right answer
