A medical researcher is comparing a person’s systolic blood pressure (measured in mmHg) in the left arm
versus the right arm. The following are measurements collected from seven subjects in both arms. At a
1% significance level, can the researcher claim the systolic blood pressure in a person’s right arm is lower
than their left arm?
Left Arm 175 169 182 146 144 128 159
Right Arm 102 103 99 88 96 113 106
a) State the hypotheses and label the claim. b) Is the test left-tailed, right-tailed, or two-tailed (circle one)?
c) What is/are the critical value(s)? Draw a picture.
d) What is the P-value and test-statistic? e) Find d and sd , round to tenths.
f) State the conclusion. Give two reasons for your decision to reject/not reject H0 based on: A. Test statistic compared to critical value B. P-value compared to α Then, relate back to the original claim.
