Question

Question 1

A binomial distribution reflects two possible outcomes, which can be denoted as "success and failure"

True

False

1 points

Question 2

As a binomial distribution is discrete, we can not ever use the normal distribution?

True

False

1 points

Question 3

The text mentions that in order to use the normal distribution for binomial distributions that EITHER n(p) OR n(q) must be > 5.

True

False

1 points

Question 4

The reason that both n(p) and n(q) are > 5 is that otherwise the distribution is likely skewed

True

False

1 points

Question 5

The reason that the distribution should not be skewed is that the normal distribution assumes that symmetrical distribtuion

True

False

1 points
