Homework Answers
Answer:
From the given study, it is observed that the correlation coefficient between the two variables travel and stress is given as 0.4. This means there is a moderate positive linear relationship or association exists between the two variables travel and stress. The correlation coefficient of 0.4 indicates a positive moderate linear relationship between the two variables. This means, when travel increases, the stress is also increases. Also, when travel decreases, the stress is also decreases.

Question 9 In a case-control study examining the relationship between hypertension and myocardial infarction, there were 20,000 participants. Half of the study subjects had hypertension. Among those with hypertension, 180 had a myocardial infarction. Among those who did not have hypertension, only 30 had a myocardial infarction. When you set up the two by two table, what is d? 180 9820 30 9970 210 19790 Question 10 In a case-control study examining the relationship between hypertension and myocardial infarction, there...

Returning to the same study examining the relationship between maternal smoking during pregnancy and congenital malformations (among children who suffer from an abnormality other than Down's Syndrome or an oral cleft, 32.8% have mothers who smoked during pregnancy), consider children born with an oral cleft. In a random sample of 27 such infants, 15 have mothers who smoked during pregnancy. a) What is a point estimate for p? Construct a 95% confidence interval for the population proportion. b) Conduct the...
