e A sprinter runs the one-hun dred-yard dash in 9. 5 seconds. What was the runner's speed in kilometers per hour?
An athletics coach states that the distribution of player run times (in seconds) for a 100-meter dash are normally distributed with a mean equal to 15.00 and a standard deviation equal to 0.2 seconds. What percentage of players on the team runs the 100-meter dash in faster than 15.48 seconds? (Round your answer to two decimal places.)
NAME: 5 pts each 10. At Ridley High School, the mean time for running the 100-yard dash is 15.1 seconds with a standard deviation of 0.8411 seconds. The times are very closely approximated by a normal curve. Find the percent of times, rounded to one deceimal place if necessary, that are: a) Less than 16 seconds (round your 2-score to 2 decimal places). b) Greater than 14.4 seconds (round your Z-score to 2 decimal places). c) Between 15.1 and 17...
