Assume a hypothesis test is performed to see if the variable MASS is helpful in explaining metabolic rate after accounting for the effects of sex. What is the correct conclusion based on the p-value given in the output?
Understand the Problem
The question is asking us to interpret the p-value from a hypothesis test regarding the variable MASS and its relation to metabolic rate, specifically after considering the variable sex. The main goal is to draw a correct conclusion from the statistical output provided.
Answer
Lean body mass helps predict metabolic rate after accounting for sex.
The correct conclusion is that there is strong evidence to indicate that lean body mass helps predict a person's metabolic rate after accounting for the effects of sex.
Answer for screen readers
The correct conclusion is that there is strong evidence to indicate that lean body mass helps predict a person's metabolic rate after accounting for the effects of sex.
More Information
The p-value for the MASS variable is less than 0.001, which is significantly below the typical 0.05 threshold used for hypothesis testing, indicating strong evidence against the null hypothesis.
Tips
Common mistakes include failing to compare the p-value with the significance level or misinterpreting what a small p-value indicates.
