a)Access the linkhttp://www.rossmanchance.com/applets/NormCalc.html

Enter Wattage for Variable Enter 353.8 for Mean.Enter 5.6 for SD.

Note: Leave the 3^rd row Mean & SD fields empty.

Click on Scale to Fit.

Select the button to the left of the first "<" symbol.Enter 348.2

Select the button to the left of the second "<" symbol.Enter 359.4

What is the probability between these two points?What are each of the corresponding z-scores?

De-select the button to the left of the second "<" symbol.

Use the applet (and your creativity and intuition) to compute the proportions of TVs that use:

b)lessthan 345 wattse) more than 362 watts

f)Televisions that are in the Top 2% percentile tend to overheat.

Focus closely on the probability part of the output to determine the wattage threshold associated with overheating.

What is the corresponding z-score?

Now answer this exercise with either the Standard Normal Table(or TI-graphing calculator) to confirm your answer.

g) Identify a benefit of using this particular statistical applet.
