1. The percentage of 12- to 17-year-olds who reported talking at least once in the past year with their parents about the dangers of drug, tobacco, or alcohol is 60% nationally. A state youth council believes this proportion is higher in their state, where there has been an intense media campaign about this issue. A survey of randomly chosen students from across the state shows 1032 of 1642 students reporting they are having these conversations with their parents. Is there evidence that the percent of students using drugs, tobacco or alcohol in this state is above the national rate?

9. There are about 8 million people in the City of New York. A survey organization took a simple random sample of 2,500 persons and found that the average household income in the sample was $59,210 and the SD was $26,120. The organization estimates the average income in the entire city to be around $59,210, they put s give-or-take number of $522.40 on this estimate. Say whether each of the following statements is true or false, and explain. (a) An approximate 99.7%-confidence interval for the average household income in the city runs from $57.642.80 to $60,777.20 (b) If a statistician takes a simple random sample of 2,500 persons out of the 8 million people in the city, and goes 3 SEs either way from the average household income of the the 2,500 people in the sample, there is about a 99.7% chance that his interval will cover the average household income in the city. (c) About 99.7% of the people in the sample had incomes in the range $59, 210+ $78,360. (d) It is estimated that 99.7% of…

I need help on these questions. The table is attached. Use Table B, starting at line 119, to choose the first 5 drivers in the sample. Drag the token representing the label of the driver selected to the appropriate column. (b) One question asked was, “Recalling the last ten traffic lights you drove through, how many of them were red when you entered the intersections?” Of the 880 respondents, 171 admitted that at least one light had been red. A practical problem with this survey is that people may not give truthful answers. What is the likely direction of the bias: do you think more or fewer than 171 of the 880 respondents really ran a red light? A) Fewer than 171 of the 880 respondents really ran a red light. B) More than 171 of the 880 respondents really ran a red light. Why would there be such a bias? A) The test suffers from sample bias. B) People may be concerned that they will get in trouble if they admit to running red lights. C) Those…
