Question

question 3
we want to explore the relationship between the prices of diamond rings and the weights of their diamond stones.
which of the following is the most appropriate statistical test to use to determine if there is a relationship between the price and weight of diamond rings?
a. anova
b. two - sample t - test
c. chi - squared test for independence
d. inference for regression
e. matched pairs t - test

Explanation:

ANOVA is used to compare means of multiple groups. Two - sample t - test compares means of two independent groups. Chi - squared test for independence is for categorical variables. Matched pairs t - test is for paired data. Inference for regression is used to explore the relationship between a response variable (price of diamond rings) and an explanatory variable (weight of diamond stones), which is what we want to do here.

Answer:

D. Inference for regression
