Please help ACT scores are normally distributed with a mean score of 21.1 and a standard deviation of 5.3. Use this information to answer the following questions.

You are applying for a scholarship that requires that your ACT score be at least at the 85th percentile. What is the lowest score that you can make and qualify for the scholarship (round to nearest whole number)?

What is the probability that a randomly selected student who took the ACT will score below 24 on the test?

You overhear your counselor saying that everyone at the school scored between the 17th and 93rd percentile on the ACT. Given that information, what was the range of ACT scores of your school?

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
