Biased means if the selection of every unit does not have an equal chance of being selected in a sample.
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.
Answer:
$6.49
Step-by-step explanation:
Pennies = 8% of 50 =4 ; 4x0.01 = 0.04
Dimes = 30% of 50 = 15 ; 15x0.10 = 1.50
Nickels = 10 + 4(number of pennies) = 14; 14x 0.05 =0.70
Quarters = 50 - 33 (total pennies + dimes + nickels ) = 17 ; 17x0.25=4.25
Therefore total amount in bag = 0.04+1.50+0.70+4.25 = $6.49
Unit price is total price/ quantity purchased.
21.16 / 4 = 5.29
Unit price = $5.29 per pair
