What is the most appropriate test statistic to use to test the hypothesis in scenario 5?

Group of answer choices:

Correlation Coefficient

Regression Analysis

Z-score

Dependent samples t-Test

P-test

One-way ANOVA

One sample Z-Test

Independent samples t-Test

What is the null hypothesis for scenario 5?

Group of answer choices:

H0: 1Keto = 2Paleo

H0: Xpaleo= Atkins

HO: 1(paleo) = 2(Keto) =3(Atkins)

HO: posttestA = pretestB

H0: rxy = 0
