A 95% confidence interval for the true proportion of teenagers who have been to a professional sporting event is (0.289, 0.416). Is it reasonable to believe that more than 25% of teenagers have been to a professional sporting event? O Yes, because 0.3525 is in the interval. O Yes, because the entire interval is greater than 0.25. O No, because there are values in the interval greater than 0.3525. O No, because the center of the interval is 0.3525, which is not statistically greater than 0.25. Save and Exit Next Submit Mark this and return % & 4 6. 7 e y f k *- 00

A survey reported in Time magazine included the question "Do you favor a federal law requiring a 15 day waiting period to purchase a gun?" Results from a random sample of US citizens showed that 318 of the 520 men who were surveyed supported this proposed law while 379 of the 460 women sampled said "yes". p is the Use this information to find a 90% confidence interval for the difference in the two proportions, p, – Pw: where Pm proportion of men who support the proposed law and p, is the proportion of women who support the proposed law. Round your answers to three decimal places. to The 90% confidence interval is
Each of the following is a confidence interval for μ = true average (i.e., population mean) resonance frequency (Hz) for all tennis rackets of a certain type: (110.6, 111.4) (110.4, 111.6) (a) What is the value of the sample mean resonance frequency? Hz (b) Both intervals were calculated from the same sample data. The confidence level for one of these intervals is 90% and for the other is 99%. Which of the intervals has the 90% confidence level, and why? O The second interval has the 90% confidence level because it is a wider interval. The first interval has the 90% confidence level because it is a narrower interval. O The first interval has the 90% confidence level because it is a wider interval.

At a certain plant, batteries are produced with a life span that is normally distributed with a standard deviation of 2 months. The plant claims that on the average the batteries will lasts for 15 months. A consumer group want to test the claim with a random sample of 27 batteries that showed an average of 14.5 months. A. What is the best point estimate for the average life span of the batteries produced by the plant: ✔ [ Select ] 27 14.5 R by the 15 2
A researcher is 95% confident that the interval from 19.7 posts to 27.3 posts captures the true mean amount of posts high school students make daily on social media. Is there evidence that the true mean number of posts high school students make is less than 27? O No. There is not evidence for the population mean to be less than 27, because 27 is within the 95% confidence interval. O No. There is not evidence for the population mean to be less than 27, because there are values greater than 27 within the 95% confidence interval. O Yes, there is evidence for the population mean to be less than 27, because 27 is within the 95% confidence interval. O Yes, there is evidence for the population mean to be less than 27, because 27 is closer to the upper bound of the 95% confidence interval than the lower bound.
