7. hypothesis testing

Question 1

test statistic def

Answer 1

result of the experiment/ statistic that is calculated from the sample

Question 2

types of hypothesis

Answer 2

null hypothesis
alternative hypothesis

Question 3

null hypothesis

Answer 3

h(0) hypothesis that you assume to be correct

Question 4

alternative hypothesis

Answer 4

h(1) hypothesis tells you about the parameter if your assumption is shown to be wrong

Question 5

one tailed tests def

Answer 5

hypothesis tests with alternative hypothesis in the form h(1) : p <… and h(1) : p >

Question 6

two tailed tests def

Answer 6

hypothesis test with an alternative hypothesis in the form
h(1) : p not equal

Question 7

too carry out a hypothesis test

Answer 7

you assume the null hypothesis is true
then consider how likely the observed value of the test statistic was to occur
the likelihood is less than the significance level of the test then you reject null hypothesis

Question 8

significance levle

Answer 8

a given threshold

Question 9

critical region

Answer 9

the region of the probability distribution which of the test falls within would cause you to reject the null hypothesis

Question 10

critical value

Answer 10

the first value to fall inside the critical region

Question 11

the actual significance levels of a hypothesis test is

Answer 11

the probability of incorrectly rejecting the null hypothesis
