I need help on how to answer question B because im not sure how to tell what to expect of the p value
Researchers want to know if there is a relationship between systolic blood pressure and heart rate in the population of all ICU patients. They collected data from a sample of 200 ICU patients and computed a correlation of r = -0.057 between systolic blood pressure and heart rate. StatKey was used to construct a 95% confidence interval of [-0.212, 0.098] for the population correlation.
A. If researchers wanted to conduct a hypothesis test to determine if there is a relationship between systolic blood pressure and heart rate in the population of ICU patients, what hypotheses would they test? State the null and alternative hypotheses that should be used. [10 points]
The researcher should use a hypothesis test for a slope or correlation. The hypothesis would be
H0: p = 0
Ha: p < 0
B. If the hypotheses from part A were tested, would you expect the p value to be less than or greater than 0.05? Explain why. (Hint: Apply the 95% confidence interval given in the scenario) [10 points]
