Answer: The probability that a randomly selected family has an income greater than $57 comma 300 = 50% or 0.50.
Step-by-step explanation:
We know that , the median is in general a middle data values in a well ordered data such that
- 50% of the data values lie below it.
- 50 % of the of the data values lie above it.
Given : The median income of families in country A was $57,300.
Then, by definition of median , we have
- 50% of the families have income less than $57,300..
- 50 % of the of the families have income greater than $57,300.
Hence , the probability that a randomly selected family has an income greater than $57 comma 300 = 50% or 0.50.
