Answer 1

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.
