You are studying how receiving free money affects someone’s blood pressure. The average systolic blood pressure is about 105, and you record 4 people who just got money and get 130, 140, 100, 110. What are your hypotheses and calculate the p-value of your experiment.
Homework Answers
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 105
Alternative Hypothesis, Ha: μ ≠ 105
Test statistic,
t = (xbar - mu)/(s/sqrt(n))
t = (120 - 105)/(18.2574/sqrt(4))
t = 1.643
P-value Approach
P-value = 0.1989

Using the t-Test Exercise Data Set Excel file, Look at the date set of Systolic Blood Pressure Normal Weight/Systolic Blood Pressure Obese Write a null hypothesis for the comparison (use the null hypothesis template). Also, write a directional hypothesis that reflects the anticipated outcome. Conduct a t-test two-sample assuming unequal variances using Excel. Interpret the Excel result (was it significant, what was the critical t-value, what was the calculated t-value, what should be done with the null hypothesis—accept or reject)....

introduction Blood pressure measurements are always expressed by two numbers, the systolic pressure over the diastolic pressure. The blood pressure cuff is inflated until the air pressure within the cuff exceeds the blood pressure in the artery in the arm. This causes the artery to collapse, temporarily shutting down the flow of blood. Then, pressure in the cuff is slowly reduced until air pressure in the cuff becomes less than pressure in the artery, allowing blood to...

Suppose you measured systolic blood pressure (unit: mmHg) of 20 individuals aged 40 to 60 living in LA, and obtained the following: 103, 115, 120, 123, 123, 128, 129, 130, 130, 132, 133, 137, 140, 140, 142, 148, 161, 165, 172, 195 Answer the following questions. (a) Is the variable measured categorical or quantitative? (b) In this situation, what is the population? Be specific. (c) Find the value of the sample mean and sample median. No need to show your...

An investigator theorizes that people who exercise regularly will have mean systolic blood pressure levels that are significantly different from those of people who do not participate in a regular exercise program. To test this idea, the investigator randomly assigns 21 subjects to an exercise program for 10 weeks and 21 subjects to a non-exercise comparison group. After ten weeks, the mean systolic blood pressure of subjects in the exercise group is 132 and the standard deviation is 10. After...

Homework Problem 5 Salt-free diets are often prescribed to people with high blood pressure. Participants were randomly selected for the study and the following data were obtained as part of a study to measure the effect on diastolic blood pressure as a result of following a salt-free diet for two weeks. Assume the differences in diastolic readings are normally distributed in the population. Did completing the salt-free diet result in a significantly different diastolic blood pressure of participants? Use a...

The data studies the effect of dietary calcium on blood pressure. In the experiment, one group of black male adults received calcium supplements for 12 weeks. A control group of black male adults was given placebos for 12 weeks. Earlier tests indicated that calcium could be more effective in the black population. The data are seated systolic blood pressure at the beginning and end of the 12 weeks measured in mm Hg. The data include the decrease after 12 weeks...
