A food company has developed a high mineral sea salt (sodium). Anurse practitioner wants to know if blood pressure can be predictedfrom the sodium intake of the new sea salt. Below are the sodiumand BP measurements for a sample of participants that regularly usethe new sea salt. What can the nurse practitioner conclude with ? =0.01?

a) What is the appropriate statistic?
---Select--- na Correlation Slope Chi-Square
Compute the statistic selected a):
b) Compute the appropriate test statistic(s) tomake a decision about H0.
(Hint: Make sure to write down the null and alternative hypothesesto help solve the problem.)
Critical value = ; Test statistic =
Decision: ---Select--- Reject H0 Fail to reject H0
c) Compute the corresponding effect size(s) andindicate magnitude(s).
If not appropriate, input and/or select "na" below.
Effect size = ; ---Select--- na trivialeffect small effect medium effect large effect
d) Make an interpretation based on theresults.
More sodium intake significantly predicts an increase in bloodpressure.More sodium intake significantly predicts a decrease inblood pressure. Sodium intake does notsignificantly predict blood pressure.
