Anything else

Question 1

What is a hypothesis test

Answer 1

A test using samples or an experiment to determine whether or not to reject the hypothesis

Question 2

What is the critical value

Answer 2

The first value to fall inside of the critical region

Question 3

The acceptance region

Answer 3

The region where we accept the null hypothesis

Question 4

The critical region

Answer 4

The region where we reject the null hypothesis

Question 5

If two events are independent

Answer 5

P(A n B) = P(A) x P(B)
P(A|B)= P(A)

Question 6

Discrete uniform distribution

Answer 6

When the probability of each outcome is the same

Question 7

When can you use binomial distribution

Answer 7

There is a fixed number of trials, there are two possible outcomes, there is a fixed probability of success, trials are independent of each other

Question 8

If two events are mutually exclusive

Answer 8

P (A n B) = 0
P (A U B)= P(A) + P(B)

Question 9

What is P(A|B)

Answer 9

It is the probability of A given that B has occurred.
P(A n B) / P(B)

Question 10

How to find P(A U B)

Answer 10

P(A) + P(B) - P(A n B) or 1 — P(A’ n B’)

Question 11

When can you use normal distribution

Answer 11

When n is large (n>50 usually)
When the p-value is close to 0.5
