Question

question 5 (1 point) listen which of the following is true about graphical data? a) all graphs should start at the origin. b) all data on a graph should be linear. c) the x - values of a graph can be estimated based on the y - values. d) graphical correlations always have a positive relationship. e) an equation of the best - fit line of data can be used to estimate untested values.

Explanation:

• Option a: Not all graphs start at the origin, e.g., graphs of data with non - zero minimum values.
• Option b: Graphs can represent non - linear data like exponential or quadratic relationships.
• Option c: This is not always possible without a known relationship between x and y.
• Option d: Graphical correlations can be positive, negative or have no correlation.
• Option e: The equation of the best - fit line (e.g., in linear regression) can be used to estimate untested values within a reasonable range.

Answer:

e) An equation of the best - fit line of data can be used to estimate untested values.
