Question

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 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	148	148	120	132	132
Left arm	185	170	187	139	154

In this example,

μd

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?

H0:

μd=0

H1:

μd≠0

H0:

μd≠0

H1:

μd=0

H0:

μd≠0

H1:

μd>0

H0:

μd=0

H1:

μd<0

Identify the test statistic.

t=nothing

(Round to two decimal places as needed.)

Identify the P-value.

P-value=nothing

(Round to three decimal places as needed.)

What is the conclusion based on the hypothesis test?

Since the P-value is

▼

less

greater

than the significance level,

▼

reject

fail to reject

the null hypothesis. There

▼

is not

sufficient evidence to support the claim of a difference in measurements between the two arms.
