Answer: 
Step-by-step explanation:
Given : Sample size : 
Sample mean : 
Standard deviation : 
Significance level : 
Critical value : 
Formula to find the confidence interval for population mean :-

Hence, a 95% confidence interval for the population mean = 
1) They are carnivores and hunt for food.
2) They are herbivores and eat plants.
3) Some (like the ant) make food by farming.
8.5x-26.35=-37.35
8.5x=-37.35+26.35
8.5x=-11
X=-11/8.5
X=-1.29
