Answer:

The standard deviation of given data is 12.36  

Step-by-step explanation:

We are given the following data in the question:

40, 12, 17, 25, 9, 46, 13, 22, 16,7

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{207}{10} = 20.7

Sum of squares of differences =

372.49 + 75.69 + 13.69 + 18.49 + 136.89 + 640.09 + 59.29 + 1.69 + 22.09 + 187.69 = 1528.1

\sigma = \sqrt{\dfrac{1528.1}{10}} = 12.36

Thus, the standard deviation of given data is 12.36

David recorded his finishing time, in seconds, for each time he ran the 100 m race during one track season. What was the median
Vikentia [17]
The median is 12.1 because it is the center number in the sequence. This only applies if the numbers are in order from least to greatest, and also if there are a even number of numbers in the sequence you must take the average of the two center ones because there is no center one.
