An athletics coach states that the distribution of player run times (in seconds) for a 100-meter dash is normally distributed with a mean equal to 13.00 and a standard deviation equal to 0.2 seconds. What percentage of players on the team run the 100-meter dash in 13.28 seconds or faster

And we can find this probability using the normal standard distribution table and we got:

And the percentage faster than 13.28 seconds would be 91.9%

Step-by-step explanation:

Let X the random variable that represent the runtimes of a population, and for this case we know the distribution for X is given by:

Where and

We want to find this probability:

And we can use the z score formula given by:

Using this formula we have:

And we can find this probability using the normal standard distribution table and we got:

And the percentage faster than 13.28 seconds would be 91.9%

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
