A coin is tossed 52 times and 37 heads are observed. Would we infer that this is a fair coin? Use a 92% level confidence interval to base your inference. The sample statistic for the proportion of heads is: (3 decimals) The standard error in this estimate is: (3 decimals) The correct 2* value for a 92% level confidence interval is: (3 decimals) The lower limit of the confidence interval is: C] (3 decimals) The upper limit of the confidence interval is: (3 decimals) Based on this confidence interval, it is --Select- v that the coin is fair. How would a 99% confidence interval compare to the 92% you constructed? C] The 99% CI would be wider. C] There is no way to tell how they would compare. C] The 99% CI would be narrower. C] They would have different centers. C] They would have the same center. An insurance company finds that of 624 randomly selected auto accidents, teenagers were driving the vehicle in 89 of them. (a) Find the 95% confidence interval for the proportion of auto accidents with teenaged drivers: ( , ) (Use 4 decimals.) (b) What does this interval mean? 0 We are 95% confident that the percent of accidents with teenaged drivers is 14.3%. 0 We are 95% confident that the proportion of all accidents with teenaged drivers is inside the above interval. 0 We are 95% confident that a randomly chosen accident with a teenaged driver will fall inside the above interval. 0 We are 95% confident that of the 624 sampled accidents, the proportion with a teenaged driver falls inside the above interval. (c) What does the 95% confidence level mean? We expect that 95% of random samples of size 624 will produce - v that contain(s) the - v of accidents that had teenaged drivers. (d) A politician urging tighter restrictions on drivers' licenses issued to teens says, "One of every five auto accidents has a teenaged driver." Does the confidence interval support or contradict this statement? 0 The confidence interval contradicts the assertion of the politician. The figure quoted by the politician is outside the interval. 0 The confidence interval supports the assertion of the politician. The figure quoted by the politician is outside the interval. 0 The confidence interval supports the assertion of the politician. The figure quoted by the politician is inside the interval. 0 The confidence interval contradicts the assertion of the politician. The figure quoted by the politician is inside the interval
