Assume that the average healthy body temperature is 98.249 degrees and the standard deviation is 0.733 degrees. How many standar
Leno4ka [110]

The standard deviation is 1.43 below the mean

<h3>How to determine the number of standard deviation?</h3>

The given parameters are:

Mean = 98.249

Standard deviation = 0.733

x = 97.2

To calculate the number of standard deviation below the mean, we use

x = \bar x - n\sigma

So, we have:

97.2 = 98.249 - n * 0.7333

Evaluate the like terms

-1.049  =- n * 0.7333

Divide both sides by -0.733

n =1.43

Hence, the standard deviation is 1.43 below the mean

No. It doesn’t, the square root is different than the approximate length.
