The graph demonstrates that the cost at private and public: c. four-year universities greatly varies.
The x-axis of the graph represents the type of school, which includes categories such as public 4-year university, private 4-year university, public community college, private community college, and technical school.
The y-axis represents the yearly cost in thousands of dollars.
According to the information given:
Public 4-year university costs $21,000 per year.
Private 4-year university costs $34,000 per year.
The significant difference between the costs of public and private 4-year universities indicates a great variation in the expenses associated with attending these institutions.
The other options can be ruled out based on the provided information:
a. Technical schools have a fixed cost of $15,000, so there is no great variation.
b. Vocational schools are not explicitly mentioned in the provided data.
d. Community colleges also have costs specified for public and private, but the difference is not as pronounced as in the case of four-year universities.
Therefore, the correct interpretation is that the graph demonstrates a significant variation in the cost of attending four-year universities, both public and private.
