x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

For a person that was 6 ft 3 in tall, he computed a 99% confidence interval for mean speed to be (4.4, 4.8). Which of these options below is the best interpretation of this confidence interval?

The the entire population(all people with this height), we are 99% confident that the mean is in this interval, so option a.
