The ratio of 7200 to 6400 equals 1.125 in decimal form. I hope this helps!:)
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 answer is D
Step-by-step explanation:V = pi (d/2)^2 * h
V = pi (d^2 / 4) * h
h = 4V / ( pi * d^2) (meters)
Answer:
x = 3.1
Step-by-step explanation:
Subtract 6.3 - 3.2 to find the value of x. You get 3.1.
