Answer:

As we know,

Standard deviation= square root variance

Standard deviation=square root 0.49

Standard deviation=square root 49/100

Standard deviation=7/10

Standard deviation=0.7

Given

  • variance 0.49

To find

  • standard deviation

Solution

we are provided with variance of the distribution as 0.49 and are expected to find the standard deviation.

From the standard equation of standard deviation we can and find the answer.

we know that standard deviation is the square root of variance of the distribution

ie, standard deviation = √(variance)

therefore,

standard deviation = √0.49

or, standard deviation = 0.7

Hence, the standard deviation of the distribution is 0.7
