Hypothesis Testing (1)

Question 1

What does H_0 represent?

Answer 1

Null hypothesis

Question 2

Null hypothesis

Answer 2

What does H_0 represent?

Question 3

What does H_1 represent?

Answer 3

Alternative hypothesis

Question 4

Alternative hypothesis

Answer 4

What does H_1 represent?

Question 5

What is the significance level?

Answer 5

The probability of incorrectly rejecting H_0

Question 6

The probability of incorrectly rejecting H_0

Answer 6

What is the significance level?

Question 7

One-tail test example

Answer 7

H_0: P = 0.6
H_1: P<0.6 or P>0.6

Question 8

H_0: P = 0.6
H_1: P<0.6 or P>0.6

Answer 8

One-tail test example

Question 9

Two-tail test example

Answer 9

P != 0.6. Significance level is halved

Question 10

P != 0.6. Significance level is halved

Answer 10

Two-tail test example

Question 11

If value is in critical region

Answer 11

Reject H_0

Question 12

Reject H_0

Answer 12

If value is in critical region

Question 13

If value is in acceptance region?

Answer 13

Fail to reject H_0

Question 14

Fail to reject H_0

Answer 14

If value is in acceptance region?

Question 15

PMCC process

Answer 15

Let p be the population correlation coefficient
H_0: p=0
H_1: p!=0

Sample product moment correlation coefficient > critical value
Fail to reject the null hypothesis

Question 16

Hypothesis test process

Answer 16

Let p be the probability of…
Define H_0 and H_1
State binomial distribution and go to binomial CD on calculator
Compare calculated probabilities with significance level
Reject or fail to reject statement
Concluding statement

Question 17

Hypothesis test process (critical region method)

Answer 17

Let p be the probability of…
Define H_0 and H_1
State binomial distribution and go to binomial CD then list on calculator
Find where the values change signs because of the critical region
State which values are in the critical region
Reject or fail to reject statement
Concluding statement
