Answer 1

Answer:b

Step-by-step explanation:

Answer 2

Given:

The variance and mean for a given set of data is 25 and 64 respectively.

To find:

The standard deviation.

Solution:

The variance and mean for a given set of data is 25 and 64 respectively.

Standard deviation and variance are both determined by using the mean of a group of numbers.

Standard deviation is the square root of the variance.

From the given data,

variance = 25

Therefore,

Standard deviation = $\sqrt{25}$

Standard deviation = 5

Final answer:

The standard deviation is 5
