Question

question 4
we want to explore the difference between salary (in dollars) and the number of years of job experience that an employee has.
which of the following is the most appropriate statistical test to use to determine if there is a relationship between salary and years of experience?
a. chi - squared test for independence
b. anova
c. matched pairs
d. two - sample t - test
e. inference for regression

Explanation:

The Chi - squared test for independence is used for categorical variables. ANOVA is for comparing means across multiple groups. Matched pairs and two - sample t - tests are for comparing means of two groups. Here, we want to explore the relationship between a continuous variable (salary) and another continuous variable (years of experience), and inference for regression is used to study such relationships.

Answer:

E. Inference for regression
