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 intervals for 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.

Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. A simple random sample of 2525 filtered 100 mm cigarettes is obtained, and the tar content of each cigarette is measured. The sample has a mean of 19.419.4 mg and a standard deviation of 3.143.14 mg. Use a 0.050.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.121.1 mg, which is the mean for unfiltered king size cigarettes. What do the results suggest, if anything, about the effectiveness of the filters? What are the hypotheses? A. Upper H 0H0: muμgreater than>21.121.1 mg Upper H 1H1: muμless than<21.121.1 mg B.
