I that the differences have a distribution that is approximately normal.
Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample
Use a 0.01 significance level to test for a difference between the measurements from the two arms. What can be concluded?
Right arm
147
143
128
135
133 -
Left arm
185
175
185
141
143
In this example, a is the mean value of the differences d for the population of all pairs of data, where each individual differenced is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative
hypotheses for the hypothesis test?
O A. Ho Ha +0
H, >0
O B. Hg: H =0
H, H <0
O C. Ho: H +0
O D. Ho: H =0
H: =0
Identify the test statistic.
t%3D (Round to two decimal places as needed.)
Identify the P-value.
P-value =(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
Since the P-value is
7 than the significance level,
V the null hypothesis. There
V sufficient evidence to support the claim of a difference in measurements between the two arms.
