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

Simple easy problem pls help

Nastasia [14]

Hello!

To find the answer, you'll first need to find how many gears that can be made in a hour. You can do this by dividing 2088 by 8. Once you've done that, there will be 261 gears being made every hour. Now you'll need to multiply 261 by 9 to see how many gears will be made n 9 hours. Once you've done that, you'll have your answer.

In 9 hours, there are 2349 gears that are made
