b. standard error of the mean
c. observed value
d. alpha level
ans-> d) alpha level
The alpha level is a probability value determined by the experimenter to define the critical values.
The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true.
When the sampling distribution of the statistic is normal or nearly normal, the critical value can be expressed as a t score or as a z-score. To find the critical value, follow these steps.
