A RECENT STUDY FINDS THAT INDIVIDUALS EATING HIGHER AMOUNT OF PROTEINS HAVE LOWER BLOOD PRESSURE. THIS IS AN EXAMPLE OF?
ANECDOTAL EVIDENCE, A HYPOTHESIS, AN INTERVENTION STUDY, A NEGATIVE OR INVERSE CORRELATION, A POSITIVE CORRELATION
Homework Answers
Answer ; A negative or Inverse correlation
Reason ; in the given example, on the one hand the study participant are directed to consume increased amount of proteins and on the other hand their blood pressure level are decreased, here we can found the increase of one variable and the decrease of another variable are correlated. Therefore the above mentioned type of study design would be the appropriate one.

A medical researcher is studying the effects of a drug on blood pressure. Subjects in the study have their blood pressure taken at the beginning of the study. After being on the medication for 4 weeks, their blood pressure is taken again. The change in blood pressure is recorded and used in doing the hypothesis test. Change: Final Blood Pressure - Initial Blood Pressure The researcher wants to know if there is evidence that the drug affects blood pressure. At...

Check our blood pressure: In a recent study, the Centers for Disease Control and prevention reported that diastolic blood pressures of adult women in the United States are approximately normally distributed with mean 80.4 and a standard deviation of 9.8. (a) What proportion of women have blood pressures lower than 657 (b) What proportion of women have blood pressures between 72 and 90? (c) A diastolic blood pressure greater than 90 is classified as hypertension (high blood pressure). What proportion...

10. According to a recent study, taller women have a significantly higher risk of developing some form of cancer. The American Cancer Society reports that approximately 38% of all women develop some form of cancer in their lifetime. A long-term Canadian study was conducted involving 1250 tall women between the ages of 50 and 79, and 502 of them developed women who develop cancer is greater than 0.38?

A study is conducted to test the hypothesis that people with glaucoma have higher than average blood pressure. The study includes 200 people with glaucoma whose mean SBP is 140 mmHg with standard deviation of 25 mmHg. What is margin of error of the mean for 95% confidence level? (Hint: Z score for 95% confidence level is 1.960).

a study is conducted to test the hypothesis that people with glaucoma have higher than average blood pressure. the study includes 30 people with glaucoma whose mean bp is 140 mm hg with a standard deviation of 24mm hg. the distribution of sbp appears to be bell shaped. you need to construct a 95% confidence interval for the true mean sbp among people with glaucoma. to help you do so, answer each of the following questions. What is the standard...

Several recent studies have suggested that people who suffer from abnormally high blood pressure can benefit from regular exercise. A medical researcher decides to test her belief that walking briskly for at least half an hour a day has the effect of lowering blood pressure. She conducts a small pilot study. If results from it are supportive, she will apply for funding for a larger study. She randomly samples three of her patients who have high blood pressure. She measures...
