Dr.Stills is interested in people's reactions to a controversial jury verdict.Dr.Stills calls people at their home between the hours of 1:00 p.m.and 3:30 p.m.on a Tuesday afternoon.In this example,what type of sample has Dr.Stills most likely selected

A)  a biased sample 
B)  a redundant sample 
C)  a bimodal sample 
D)  a representative sample

By calling people at their homes during specific hours on a specific day, Dr. Stills is likely to reach only a subset of the population that may have different attitudes or circumstances than the broader population. This could potentially introduce bias into the sample, as those who are home at that time may not be representative of the population as a whole. Additionally, those who choose to answer the call may have different opinions than those who do not answer or are not reached, further biasing the sample.
