Biology and Environmental Science A hand is a traditional unit used to measure the height of a horse. One hand is four inches, and the height of a horse is measured from the ground to the horse's shoulder. A random sample of horses sold at auctions around the country revealed the following heights (in hands).
a. Find a point estimate for the population mean height of all horses sold at auctions.
b. Find a point estimate for the population median height of all horses sold at auctions.
c. Find a point estimate for the population variance of the height of all horses sold at auctions.
d. Any horse with a height less than 14.5 hands is considered short. Find a point estimate for the true proportion of short horses sold at auctions.
