Question 10

Type 1 Error

Answer 10

is produced by a lenient probability - probability that results were due to chance and therefore accept the research hypothesis when we should’ve rejected it

Type 2 Error

Answer 11

produced by a stirct probability - probability that there was no effect when there was and therefore we accept the null hypothesis when we should’ve rejected it
