The Bloom Biscuit Company is planning a marketing strategy for the upcoming year. They plan on doing a survey to see how many residents in their state bake. Marketing assistants randomly call homes during their 9:00 a.m.–5:00 p.m. work shift, and find out that 79% of people they speak to bake. Do you think this is an overestimate, underestimate, or good approximation of the actual population percent of people who bake? Explain.
