A health care professional wants to determine whether
individuals with hypertension who take Atenolol have significantly
lower systolic blood pressure than individuals with hypertension
who do not take Atenolol. For individuals who have not been
prescribed Atenolol, the population systolic blood pressure mean is
165 (µ = 165). The 234 individuals who take Atenolol have an
average systolic blood pressure of 147, with a sample standard
deviation of 8.47. On the basis of these data, can the researcher
conclude that the Atenolol significantly lowers systolic blood
pressure? (Use these numbers only for this
question!)
What is the numeric value of your standard error?
s = 8.47 , n = 234
Standard error = s/sqrt(n)
= 8.47/sqrt(234)
= 0.5537
standard error = 0.5537

A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 155 (µ = 155). The 33 individuals who take Atenolol have an average systolic blood pressure of 145, with a sample standard deviation of 24. On the basis of these data, can the researcher conclude that...
A health care professional wants to determine whether individuals with hypertension who take Atenolol have significantly lower systolic blood pressure than individuals with hypertension who do not take Atenolol. For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 171 (µ = 171). The 30 individuals who take Atenolol have an average systolic blood pressure of 144, with a sample standard deviation of 23. On the basis of these data, can the researcher conclude that...

For individuals who have not been prescribed Atenolol, the population systolic blood pressure mean is 168 (µ = 168). The 30 individuals who take Atenolol have an average systolic blood pressure of 107, with a sample standard deviation of 11. On the basis of these data, can the researcher conclude that...
In the journal Hypertension of the American Heart Association, researchers report that individuals who practice Transcendental Meditation (MT) lower their blood pressure significantly. If a random sample of 225 men who practice TM meditate 8.5 hours a week. The population standard deviation is known to be 2.25 hours, does this suggest that, on average, men who use TM meditate more than 8 hours per week? Use a significance level of 0.02. The hypotheses would be: a) Ho: µ = 8...

Hypertension is also called the silent killer as many do not have symptoms until it is too late. This is a huge health concern and one which supports individuals having yearly visits to their health care professional. Changes in diet, exercise and stress can help reduce elevated blood pressure, but there are many who also need to be on anti-hypertensive medication. If you are in charge of a public health program on hypertension, what types of discussion would you include?
Marcus is a 44-year-old African-American man who has been seen twice in a health care clinic for “blood pressure” problems. At the first visit, his blood pressure was 144/90 mm Hg; at the second visit, his blood pressure was 154/96 mm Hg. The provider is preparing to start antihypertensive medications. Two years later Marcus is diagnosed with Type 2 diabetes. His blood pressure is 130/86 mm Hg on his current medications. Marcus is now prescribed captopril. Marcus states that he...
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...
