Question

The following are the ages in years (X) and systolic blood pressures (Y) of 8 apparently healthy adults: Age (X) SBP (Y) 20 120 43 130 60 140 26 126 53 143 31 133 55 146 46 132 Calculate Pearson's correlation coefficient between age (X) and systolic blood pressure (Y). B. Conduct a hypothesis test to investigate whether there is a significant linear relationship between X and Y, using Î±= .05. State your null and alternative hypotheses and the conclusion.

          The following are the ages in years (X) and systolic blood pressures (Y) of 8 apparently healthy adults:

Age (X)   SBP (Y)
20           120
43           130
60           140
26           126
53           143
31           133
55           146
46           132

Calculate Pearson's correlation coefficient between age (X) and systolic blood pressure (Y).

B. Conduct a hypothesis test to investigate whether there is a significant linear relationship between X and Y, using Î±= .05. State your null and alternative hypotheses and the conclusion.
