Answer: d .we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Step-by-step explanation:
- A x% confidence interval interprets that a person can be x% sure that the true population parameter lies in it.
Given : Veterinary researchers at a major university veterinary hospital .
He calculated a 99% confidence interval for the average age of horses admitted for laminitis, a foot disease that leaves the horse severely lame, as 6.3 to 7.4 years.
Here , Population parameter = Mean age of horses with laminitis
Interpretation: We are 99% sure that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Hence, the correct option is d .we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Answer:
The answer is m=12
Step-by-step explanation:
1.) combine like terms on both sides of the equation.
2.) After all like terms are combined, divide 250 from both sides.
3.) m=12
I think the answer could be 10 or even 12

we can treat this like simple addition and subtraction
3+5=8
8-2=6
6-1=5
