20th percentile = 16th smallest value
60th percentile = 48th smallest value.
You can't do this without knowing the distribution of scores.
To convert your 1979 ACT score to percentile scores, you can reference historical data from the ACT organization, which provides percentile ranks for various scores. You may need to find a specific ACT score percentile table from that year, as percentiles can change annually based on the performance of test-takers. Alternatively, tools or resources that aggregate historical ACT data can help you identify the corresponding percentile for your score. If you cannot find specific data from 1979, you might consider using more recent percentile data as a general guide, keeping in mind that it may not be perfectly accurate for that year.
From the given information it is not possible. You need to find the score, S, such that the percentage of people scoring S or below is 40%.

Use =PERCENTILE(range,0.85) where range is the data that you want to analyse.

it doesn't exist.

First let's define both, that will help to see the difference.1.A percentile is a measure that lets us know what percent of the total frequency scored below that measure. A percentile rank is the percentage of scores that fall below a given score. Here is how that works.Given a score, call it S and a total of n scores we are looking at, we find the number of scores below S and divide that by n. Next multiply that by 100 and you have the percentile rank.Now a z score is the number of standard deviations from the mean.Say the mean is M and your score is S as above. Let sigma be the standard deviation of the distribution. Then z=(S-M)/sigma.So let's say the mean M is 100 and sigma is 15. S is 132, you did better than average!So z=(132-100)/15=2.13If 60 percent of the people scored less than you, then you are in the 60th percentile.Furthermore, lets say, there were 100 people taking test, then 60 of them scored less than you. Your percentile ranking is (60/100)x100=60So both are measures of where your results falls in a distribution. z scores are often used for probability of a certain result. Percentile ranks are often used in looking at standardized test results or growth data. One can convert from one to the other.I have given a conversion table link belowhttp://www.acposb.on.ca/conversion.htm

find the median of the set of data. and then find the quartiles. Q1 would be the 25th and Q3 would be the 75th

You can use the percentile function with values that are multiples of .10 in the function. Say your values were in the cells A2 to A50, you could use these functions for some of the different deciles: =PERCENTILE(A2:A50,0.1) =PERCENTILE(A2:A50,0.2) =PERCENTILE(A2:A50,0.3) =PERCENTILE(A2:A50,0.4)
Use =PERCENTILE(range,0.85) where range is the data that you want to analyse.
