a. A one-sided test is used whenever the sample size is small.
b. If alpha = .05, it means that if Ho is true, the chance of falsely rejecting it is maximum 5%.
c. If the P-value is .04, and the significance level alpha = .05, then we will reject Ho.
d. A hypothesis test is performed, and the data were found to be statistically significant at alpha = 5%. Then data will be significant at 1% also.
e. Increasing alpha increases the critical value.
f. Decrreasing alpha increases the area of the critical region.
