Samples of two different models of cars were selected, and the actual speed for each car was determined when the speedometer registered 50 mph. The resulting 95% confidence intervalsfor true mean actual speed were (51.2, 52.6) and (49.2, 50.4). Assuming that the two sample standard deviations are equal, which confidence interval is based on the larger sample size?O (51.2, 52.6)O (49.2, 50.4)Explain your reasoning.O As the sample size increases, the width of the interval increases.O As the sample size increases, the width of the interval decreases.
