Answer to Problem 1CYU
The median of the data to the nearest tenth is
Explanation of Solution
Given information: The table is given below shows the speeds of Indianapolis 500 in recent year:
Year | Driver | Speed (mph) |
2001 | HelioCastoneves | 131 |
2002 | HelioCastoneves | 166 |
2003 | Gil de Ferran | 157 |
2004 | Buddy Rice | 139 |
2005 | Dan Wheldon | 158 |
2006 | Sam HornishJr | 157 |
2007 | Dario Franchitti | 152 |
Calculation:
The sum of given data divided by the total number of items in the set is known as the mean of the data.
To find the mean of the data, divided the sum of speed in different years by the number of years.
The mean of the data to the nearest tenth is
The middle number of the given data arranged from least to greatest number is known as the median of the data.
To find the median of the data, arrange the speed from least to greatest.
The median of the given data is 157.
The number that occurs more than once in the given data is known as the mode of the data.
In the given data, the number 157 occur twice. So, the mode is 157.
Therefore, the median of the data to the nearest tenth is
