Question

The top 14 speeds, in miles per hour, for Pro-Stock drag racing over the past two decades are listed below. 181.1 202.2 190.1 201.4 191.3 201.4 192.2 201.2 193.2 201.2 194.5 199.2 196.0 196.2 Find the median speed to one decimal place.

Answer 1

We conclude that the median speed is 195.8.

Explanation:

We have the top 14 speeds, in miles per hour, for Pro-Stock drag racing over the past two decades

We have: 181.1 202.2 190.1 201.4 191.3 201.4 192.2 201.2 193.2 201.2 194.5 199.2 196.0 196.2.

To calculate the mean speed, we will sum all the speeds and divide by the number 14, because that is the total number of speeds.

`x=(181.1+ 202.2 +190.1 +201.4+ 191.3+ 201.4+ 192.2+ 201.2+ 193.2+ 201.2+ 194.5+ 199.2+ 196.0 +196.2)/(14)\\\\x=(2741.2)/(14)\\\\x=195.8`

We conclude that the median speed is 195.8.
