Answer:
c. 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:
Given that veterinary researchers at a major university veterinary hospital 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.
i.e. if X is the age of horses admitted for laminitis then the sample mean i.e. x bar follows a distribution with 99% confidence interval as
(6.3,7.4)
The interpretation of 99% confidence interval is the for sample of large size drawn at random from population we can be 99% confident that the sample mean will fall within this interval.
So the correct option is
c. we are 99% confident that the true mean age of horses with laminitis is between 6.3 and 7.4 years old.
Answer:
The area of the rectangle is 
.
Step-by-step explanation:
The perimeter of a rectangle is
where, L is length and W is width.
It is given that perimeter of a rectangle is 10m.
Divide both sides by 2.
Subtract L from both sides.
Area of a rectangle is
Substitute W=(5-L) in the above formula.
Therefore, the area of the rectangle is .
