Scenario 2.A researcher is interested in examining whether doctors are as accurate at diagnosing certain illnesses via telehealth as they are in person. She randomly assigns doctors to either see patients via telehealth or in person, and assesses their diagnostic accuracy.

What is the most appropriate test statistic to use to test the hypothesis in scenario 2?

Group of answer choices:

Factor Analysis

Independent samples t-Test

Correlation Coefficient

Dependent samples t-Test

Structural Equation Model

One-way ANOVA

z-test

z-score

What is the null hypothesis for scenario 2?

Group of answer choices:

H0: rxy= 0

H0: 1(telehealth) = 2(in person) =3(control)

H0: 1Telehealth = 2In-Person

H0: telehealth

in-person

What is the alternative hypothesis for scenario 2?

Group of answer choices:

H1: 1(telehealth) 2(in person) 3(control)

H1: x

H1: m1Telehealth m2In Person

H1: rxy = 0
