Question

Answers all questions. Include a written part as well as the JASP results in your answer. Make sure you explain the answer not just give the result in F,df and p values. No need to include assumptions. A researcher in a women’s clinic was interested in knowing if there was any difference in systolic blood pressure measurements (mm Hg) if they took a measurement on the right arm or if they took the measurement on the left arm. 10 female adult participants were selected where a blood pressure measurement was taken on the right arm and then on the left arm 15 minutes later. Determine if there was a difference in blood pressure measurements depending on the arm chosen. Use a significance level of .05. Include hypotheses. Write up in the correct way. Right Arm Left Arm 102 175 101 169 94 182 79 146 79 144 115 150 110 134 127 147 136 158 109 165

Answer 1

Using Excel

data -> data analysis -> t-Test: Paired Two Sample for Means

since p-value = 0.0001 < alpha

we reject the null hypothesis

we conclude that there is signficant difference
