Distribution with a mean of 100 and standard deviation of 15...

1 answer:

8 0

Use the z-score:
112 - 100
For 112, the z-score is --------------- = 12/15, or 0.8.
15

Next, find the AREA under the standard normal curve TO THE LEFT OF 0.8.

Use either a z-score table or a calculator for this purpose.

Using my calculator, I found that this area is 0.532. That places 112 in the 53rd percentile.

82 would be in a lower percentile: the 12th percentile.

Let me know if you have questions about how to use a calculator to do these calculations.

How to round off to the neares<br> t degree

lyudmila [28]

Answer:

Step-by-step explanation:

How to round off to the nearest degree

lets pick this number: 3,266.528

first let round to the nearest whole number by thousand

lets remove the .528 because we don’t need it

3,266

4000-3266 is 734

3,266 minus 3000 is 266

so rounded to the nearest thousand in the whole number is 3,000

or let’s say hundredths

3266.528

0.3- 0.28 is 0.3

0.28 - 0.2 is 0.8

so rounded to the nearest hundredth is 3,266.53

hope this helps :)

You are part of the research group that hypothesized that relative humidity played a role in the transpiration differences. What

aleksandrvk [35]

Answer:

<h2>A) Population A has a high water potential and loss due to transpiration because of the increased humidity.</h2>

Step-by-step explanation:

Notice that the hypothesis is that relative humidity affects the transpiration of the body. So, in order to prove such hypothesis, we need to find enough evidence about water loss due to higher humidity. Knowing the relative humidity as the relation between water vapor and the pressure of it.

Therefore, the right answer is A, because we need to prove that a high water potential and loss due to transpitation happens because of the increased humidity.
