Question

1. Briefly discuss the difference between the "Alpha level" (α) and the "p-value".

2. True or False: Reject the null hypothesis when α = 0.042 and p-value = 0.03

3. True or False: Retain the null hypothesis when α = 0.02 and p-value = 0.010

4. True or False: Reject the null hypothesis when α = 0.01 and p-value = 0.005

5. True or False: Retain the null hypothesis when α = 0.001 and p-value = 0.02

Answer 1

We reject the null hypothesis if p-value <

a)

Since p-value < 0.042 , reject null hypothesis.

TRUE

b)

Since p-value < 0.02, Reject null hypothesis.

False

c)

Since p-value < 0.01, reject the null hypothesis.

True

d)

Since p-value > 0.001 , retain the null hypothesis.

True.
