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?

Is there a relation between murder and arson? A random sample of 15 Midwest cities (over 10,000 population) gave the following information about an annual number of murder and arson cases. (Reference: Federal Bureau of Investigation, U.S. Department of Justice.)

(a) Rank-order murder using 1 as the largest data value. Also, rank-order arson using 1 as the largest data value. Then construct a table of ranks to be used for a Spearman rank correlation test.

Regarding the context regarding the coronavirus pandemic, see the table below, which refers to 5 groups of people infected with the coronavirus and the number of deaths in each group. a) You, student, by observing the data tabulated in the table above, come to what conclusion about the absolute frequency of the second grade? b) João, a person observing the table, calculates and states that the relative frequency of the fourth class is 48.46% and informs that 48.46% of the number of deaths occurred in the group with the number greater than or equal to 70 and less than or equal to 80 infected. Do you agree with João's calculation and interpretation? If you agree or disagree, provide the calculation and interpretation that justifies your choice. c) Going deeper, Maria, another person who looks at the table, interprets that 16 deaths occurred in the group with a number greater than or equal to 40 and less than 70 infected people.

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…
