Answer: We can be 95% confident that the true proportion of all college students gain weight in their freshman year.
Step-by-step explanation:
- A 95% confidence interval interprets that a person can be 95% confident that the true population parameter lies in it.
Given : A popular claim, nicknamed "freshman fifteen," states that many college students gain weight in their freshman year.
The 95% confidence interval as 55.9% < p < 78.4%.
Here : Population parameter = p , where p is the proportion of college students gain weight in their freshman year.
Interpretation of 95% confidence interval : We can be 95% confident that the true proportion of all college students gain weight in their freshman year.
