Question

A scientist wants to know if adults prefer watching movies in a theater or in their home. He interviews 500 people leaving a local movie theater and finds that 480 of them like watching movies in theaters. The scientist concludes that 96 percent of people like watching movies in theaters more than at home. Why is the scientist's conclusion most likely unreliable?

Answer 1

Answer:

The scientist's conclusion is most likely unreliable because he just interviewed people watching movies in the theatre. He should have interviewed an equal number of people from the theatre and from home to get reliable results. According to the scientific method for designing an experiment, the experiment or survey conducted by scientists is not correct. Hence, the scientist's conclusion is wrong because his method of experimentation was wrong.
