What is the null hypothesis in hypothesis testing?
The hypothesis we want to prove
The hypothesis we want to discredit
A statement about the sample mean
A hypothesis unrelated to the population
What is the significance level denoted by α in hypothesis testing?
The probability of rejecting the alternative hypothesis

What is a one-sided test?
A test where the hypothesis is non-directional
A test where the null hypothesis is rejected for either high or low values
A test where the hypothesis specifies a parameter greater or less than a certain value
A test that does not involve sample statistics
What test is used if we do not know the variance of a population?
