A medical researcher wants to begin a clinical trial that
involves systolic blood pressure (SBP) and cadmium (Cd) levels.
However, before starting the study, the researcher wants to confirm
that higher SBP is associated with higher Cd levels. Below are the
SBP and Cd measurements for a sample a participants. What can the
researcher conclude with an α of 0.01?
SBP | Cd |
---|---|
169 161 115 113 182 126 179 127 148 160 140 |
56.6 55.7 55.7 55.5 55.9 55.8 55.8 55.5 55.7 55.8 55.6 |
a) What is the appropriate statistic?
---Select--- na Correlation Slope Chi-Square
Compute the statistic selected above:
b) Compute the appropriate test statistic(s) to
make a decision about H0.
(Hint: Make sure to write down the null and alternative hypotheses
to help solve the problem.)
critical value = ; test statistic =
Decision: ---Select--- Reject H0 Fail to reject H0
please leave a comment if there is any doubt. The paired t test is appropriate for this problem.

A pharmaceutical company.claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d (blood pressure before taking new drug)-(blood pressure after taking new drug). Use a significance level of a 0.05 for the test. Assume that the systolic blood pressure levels are...
A study looked at the relationship between alcohol consumption and level of systolic blood pressure (SBP) in women not using oral contraceptives (OC). Alcohol consumption was categorized as follows: no alcohol use; s 10 oz/week alcohol consumption; > 10 oz/week alcohol consumption. The results for the SBP measurements for women 30-39 years of age are given below. Group A. No Alcohol Use B. s 10 oz/week alcohol consumption C. > 10 oz/week alcohol consumption Mean var 105.3 10.6 110.4 13.4...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d=(blood pressure before taking new drug)−(blood pressure after taking new drug). Use a significance level of α=0.1 for the test.

A clinical trial is planned to compare an experimental medication designed to lower blood pressure to a placebo. Patients are enrolled and randomized to either the experimental medication or the placebo. The data shown below are data collected at the end of the study after 6 weeks on the assigned treatment. Experimental (n=100) Placebo (n=100) Mean (SD) Systolic Blood Pressure 120.2 (15.4) 131.4 (18.9) % Hypertensive 14% 22% % With Side Effects 6% 8% Is there a significant difference...
