As the sample size increases, we assume:
a. α increases
b. β increases
c. The probability of rejecting a hypothesis increases
d. Power increases
d. Power increases
a. α increases
b. β increases
c. The probability of rejecting a hypothesis increases
d. Power increases
d. Power increases
- Power increases if the standard deviation is smaller.
- If the difference between the means is bigger, the power is bigger.
- Sample size also increases power
