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....

5. Researchers conducted a naturalistic study of children between the ages of 5 and 7 years. The researchers visited classrooms during class party celebrations. As a measure of hyperactivity, they recorded the number of times children left their seats The researchers found a strong positive correlation between sugary snacks offered at the parties and hyperactivity. Based on these findings, the researchers concluded that sugar causes hyperactivity. a. Explain why people may easily accept the conclusion of the study described above?...

10A) Give an example of a paired data set (with at least 5 pairs) that demonstrates a strong (but not perfect) negative linear correlation. x y 10B) Give a real life example of two variables that are likely to be positively correlated. Specifically explain why you believe your chosen two variables are positively correlated. 10C) Suppose some researchers studied children in high schools and found a strong positive linear correlation between the availability of vending machines and obesity. From this...

QUESTION 10 A study on diet and weight found that the correlation coefficient between weight and daily serving of vegetables and fruits is -0.6. What does this mean? 1. Weight increases as daily intake of vegetables and fruits increases 2. Weight decreases as daily intake of vegetables and fruits increases 3. Lower intake of vegetables and fruits causes overweight 4. Higher intake of vegetables and fruits causes overweight

QUESTION 1 Tamiflu is a drug used to treat influenza. A study found that Tamiflu reduced symptom duration an average of 0.85 days in otherwise healthy (i.e., not high risk) individuals. The researchers reported a 95% confidence interval for the reduction in symptom duration of 0.3 to 1.4 days. Which is a correct interpretation of this result? Choose all that apply. A. There is a 95% chance that the true mean reduction in symptom duration is between 0.3 and 1.4...

1 3 5 N A decade-old study found that the proportion of high school seniors who felt that "getting rich" was an important personal goal was 73%. Suppose that we have reason to believe that this proportion has changed, and we wish to carry out a hypothesis test to see if our belief can be supported. State the null hypothesis Ho and the alternative hypothesis H, that we would use for this test. 11 IX P o S 0 0...

A study was conducted on students from a particular high school over the last 8 years. The following information was found regarding standardized tests used for college admitance. Scores on the SAT test are normally distributed with a mean of 1087 and a standard deviation of 199. Scores on the ACT test are normally distributed with a mean of 19 and a standard deviation of 5.1. It is assumed that the two tests measure the same aptitude, but use different...
