More on Normal Distributions

Question 1 out of 5.

Suppose you have a normal distribution with a mean of 6 and a standard deviation of 1. What is the probability of getting a Z score of exactly 1.2?

Question 2 out of 5.

You decide to use the normal distribution to approximate the binomial distribution. You want to know the probability of getting exactly 6 tails out of 10 flips. First you find the mean and SD of the normal distribution, and then you compute the area:

at exactly 6
from 5.5 to 6.5
from 0 to 6
from 6 to 10

Question 3 out of 5.

You decide to use the normal distribution to approximate the binomial distribution. You want to know the probability of getting from 7 to 13 heads out of 20 flips. You compute the area:

from 7.5 to 13.5
from 7.5 to 12.5
from 7 to 13
from 6.5 to 13
from 6.5 to 13.5

Question 4 out of 5.

The normal approximation to the binomial is most accurate for which of the following probabilities?

Question 5 out of 5.

The normal approximation to the binomial is most accurate for which of the following sample sizes?
