Time Remaining: 03:11:34 Submit Qu his Question: 1 pt This Quiz: 6 pts possib 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 isa simple random sample and that the differences have a distribution that is approximately normal Use a 0.10 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 150 149 136 129 139 Left arm 177 168 182 151 142 In this example, po is the mean value of the differences d for the population of all pairs of data, where each individual difference d 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? ts Identity the test statistic. I- (Round to two decimal places as needed ) 57 dia Librar 0 oz

Explanation / Answer

The statistical software output for this problem is:

Paired T hypothesis test:
D = 1 - 2 : Mean of the difference between Right Arm and Left Arm
H0 : D = 0
HA : D 0
Hypothesis test results:

Hence,

Hypotheses: Option C is correct.

t = -3.38

P - value = 0.028

Less; reject; is
