Question

Pls help me ASAP!!!!!!!

Answer 1

The standard deviation is 5.83 kg

Explanation:

Variance and Standard Deviation

Given a data set of random values, the variance is defined as the average of the squared differences from the mean. We use this formula to calculate the variance:

`\displaystyle \sigma^2=(\sum(x_i-\mu)^2)/(n)`

Where
`\mu` is the mean of the values xi (i=1 to n), n the total number of values.

The standard deviation is known by the symbol
`\sigma` and is the square root of the variance.

We are given the value of the variance:

`\sigma^2=34\ kg^2`

We now compute the standard deviation

`\sigma=√(34\ kg^2)=5.83\ kg`

The standard deviation is 5.83 kg
