DUl as a probability distribution that is ped" when graphed. Draw a rough sketch of the distribution is informally bell shape t 3 Random Digits. that characterizes normal distributions. Normal Va sets in Eu Digits. Many states have lotteries that involve the 0, 1,2,.... 9. Is the distribution 3. you wou of those digitsa normal distribution? why orwhy not,MO reas. Birth weights in the United States are normally dis- tributed 11. w ted with a mean (in grams) of 3420 g and a standard tion of 495 g. If you graph this normal distribution, rea to the right of 4000 g is 0.12. What is the area to the left of 4000 g? It Make Sense? For Exercises 5-8, decide whether the Does statement makes sense (or is clearly true) or does not make (or is clearly false). Explain clearly; not all of these have efinitive answers, so your explanation is more important tha our chosen arswer ,. Heights of Women. A sample of 2,000 women is randor

Explanation / Answer

Total area under standard normal curve is 1.

So, P(X>x)=1-P(X<x)

Given area to the right of 4000 is 0.12

So, Area to the left= 1-Area to the right

= 1-0.12

=0.88

Area to the left of 4000 = 0.88
