4.A college football scout was interested in seeing if a football players height was a good predictor of how fast they were. He randomly sampled 15 different football players and recorded both their heights and their 40 yard dash times. 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?

A.) It can be stated with 99% confidence that the mean speed for players who are 6 ft 3 in tall is between 4.4 and 4.8 seconds.

B.) 99% of the time a player will run the 40 yard dash in between 4.4 and 4.8 seconds.

C.) 99% of all players are 6ft 3in tall.

D.) It can be stated with 99% confidence that out of the 15 football players sampled those who were 6ft 3in tall averaged between 4.4 and 4.8 seconds in the 40 yard dash.
