Question

The time for a 100-meter dash at a college track meet were 10.62, 10.48, 10.78, 10.76, 10.96, 10.88, 10.97, 10.4, 10.35, and 11.10 seconds. Calculate:

a) Mean time for the 100-meter dash.

b) Median time for the 100-meter dash.

a) 10.69s

b) 10.82s

c) 10.76s

d) 10.88s

Answer 1

The mean time for the 100-meter dash is 10.732 seconds. The median time for the 100-meter dash is 10.78 seconds.

Step-by-step explanation:

To calculate the mean time for the 100-meter dash, you need to add up all the individual times and divide by the total number of times. In this case, the sum of the times is 107.32 seconds and there are 10 times in total. So, the mean time is 107.32/10 = 10.732 seconds.

To calculate the median time for the 100-meter dash, you need to arrange the times in ascending order and find the middle value. In this case, the times in ascending order are: 10.35, 10.4, 10.48, 10.62, 10.76, 10.78, 10.88, 10.96, 10.97, 11.1. The middle value is the 6th time, which is 10.78 seconds .
