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.
