A researcher asks: Are high school students who have tried
alcohol more likely to have had sex than students who have never
had alcohol? Using the data from the YRBS study, the researcher
finds that only 16.7% of high school students who have never tried
alcohol have had sex, whereas 56.3% of high school students who
have tried alcohol have had sex. Based on these findings, the
researcher concludes that drinking alcohol causes high school
students to have sex.
What is the explanatory variable?
Group of answer choices
high school students
Whether or not they have ever tried alcohol
In the example above, what is the response variable?
Group of answer choices
high school students
Whether or not they have ever tried alcohol
Whether or not they have ever had sex
56.3% of high school students who have tried alcohol
Whether or not they have ever had sex
56.3% of high school students who have tried alcohol
Here whether or not a student have had sex is the dependent variable and whether or not a student have tried alcohol is independent.
Because sex depends on a person having tried alcohol.
Explanatory variable is another name of independent variable. So the answer is whether or not they have tried alcohol
Response variable is another name of dependent variable. So the answer is whether or not they have ever had sex

In a study of high school students at Mumford High, it was found that 75% of those students who drank two or more beers each day for a period of 60 days experienced measurable liver hnction deterioration. That these results could have occurred by chance was ruled out experimentally with high levels of confidence." 20. If true, the Mumford High information would confirm that A= Drinking is statistically correlated with liver deterioration in adolescents. B=Drinking causes liver deterioration in adolescents....
A researcher is interested in assessing the association between smoking behaviors and alcohol consumption among college students. The researcher surveys undergraduate students in public health classes and asks them whether or not they are current smokers and whether or not they consume any alcohol. The researchers end up with 500 completed surveys. Of the 500 students who participated, 125 had ever smoked and 367 have ever consumed alcohol. Of the 125 that had ever smoked, 105 also consumed alcohol. Complete...

A researcher is interested in determining if a new intensive treatment program for high school students with alcohol abuse problems is effective. In order to recruit participants for this study, flyers are mailed to all families of high school students in the Northwest Arkansas area. Ninetythree families decide to participate in the study. To test the main research hypothesis, the families are randomly assigned to one of three groups, with the restriction that an equal number of families are in...
A researcher believes that the proportion of male high school seniors who have their own cars is higher than the proportion of female high school seniors who have their own cars. In a sample of 35 male high school seniors 10 had their own cars. In a sample of 40 female high school seniors, 10 had their own cars. At α = 0.05, test the researchers claim using the five step testing method.
1. A university researcher is interested in whether efforts to recruit more top high school students have been successful. To test this, she randomly selects 50 freshmen from the university and records their high school GPA. The mean is 2.75 with a standard deviation of 0.50. The researcher also knows that the mean high school GPA of all freshmen enrolled at the university five years ago was 3.00 with a standard deviation of 0.66. The researcher wants to know if...
A researcher is interested in whether students who are musicians have higher intelligence scores than those in the general population. The researcher predicts that playing a musical instrument is associated with higher intelligence test scores. The researcher selects a sample of 75 musicians from local high schools and gives them an intelligence test. She compares their average intelligence to that of students in the general population and finds that zobt = +1.92. This is a _____ test and the researcher...

A researcher wants to determine whether high school students who attend an SAT preparation course score significantly different on the SAT than students who do not attend the preparation course. For those who do not attend the course, the population mean is 1050 (? = 1050). The 16 students who attend the preparation course average 1200on the SAT, with a sample standard deviation of 100. On the basis of these data, can the researcher conclude that the preparation course has...
