According to sales information in the first quarter of 2019, 11% of the new vehicles sold in the United States were hybrids. Let’s assume these statistics remain the same for 2020. That is, 11 percent of the new car sales are hybrids in the first quarter of 2020. For a sample of 52 vehicles sold in the Richmond, Virginia area, what is the probability that:
More than 6 were hybrids? (Round your z-score computation to 2 decimal places and final answer to 4 decimal places.)
At least 6 were hybrids? (Round your z-score computation to 2 decimal places and final answer to 4 decimal places.)
Exactly 6 were hybrids? (Round your z-score computation to 2 decimal places and final answer to 4 decimal places.)
