Hypothesis Testing

Question 1

Population parameter

Answer 1

A statistical measure relating to a population. E.g. the mean is a population parameter

Question 2

Hypothesis

Answer 2

A hypothesis is a state,not made about a population parameter

Question 3

Null hypothesis

Answer 3

The ‘default’ position which we usually assume to be true. E.g. rolling a five getting a 6, H0: P = 1/6

Question 4

Alternative hypothesis

Answer 4

The hypothesis tells us about the parameter/situation if our null hypothesis turns out to be incorrect. E.g. for rolling a dude and getting a 6, H1: P =/ 1/6

Question 5

Test statistic

Answer 5

The result of the experiment we are using, which we use to test H0. E.g. if we tossed a coin 4 times and got heads 3 then that value/ proportion is the test statistic
