14 mi 2 hr
Cross multiplying, we get 2x = (1/4)(14), or
x = (1/4)(7), or x = 7/4
Steve can jog 7/4 miles in 1/4 hour. That's 1 3/4 miles in 1/4 hour.

The sample is said to be good if choosing the unit is unbiased. The sample is said to be unbiased if the selection of each unit is independent.
Option A is an example of data selected in a biased way because principal chose only those student who scored the highest marks on reading test.
Options B and C are unbiased as here a selection of each number and name of the student has an equal chance of being selected.
Option D is biased because Sergio talked adults at a local fitness center where people go for maintaining their health. So, there is a chance of the selection of fitted adults more than unfitted adults.
Option E is biased because Josh met people at the dog park where dog lovers are more than a cat lover.
