Answer:
About 1.5
Step-by-step explanation:
We can round 4/5 to 1.
We can round 3/8 to 4/8 = 1/2.
So our estimate is
4/5 + 3/8 =
about 1 + 1/2 = 1.5
(Shh... let's check using the calculator... it's 1.2. We were pretty close!)

Using sampling concepts, one sample of 5 high schools in the city of Chicago is given by:
Brooks, Hyde Park, Young Womens, Marshall, Noble - UIC.
<h3>What is the missing information?</h3>
The problem is incomplete, but researching it on a search engine, it gives us a list of 15 high schools in Chicago, and asks us to take a sample of 5.
<h3>What is population and sample?</h3>
- Population: Collection or set of individuals or objects or events whose properties will be studied.
- Sample: The sample is a subset of the population, and a well chosen sample, that is, a representative sample will contain most of the information about the population parameter. A representative sample means that all groups of the population are inserted into the sample.
Hence, from the concepts of sample and populations, the sample of 5 means that we have to select 5 schools from the 15 listed, hence one possible option is given by:
Brooks, Hyde Park, Young Womens, Marshall, Noble - UIC.
