Based on what you know about how this sample was collected, the sample is a random sample from the populations of interest. The second assumption requires the sample to be large enough to be reasonably sure that the sampling distribution will be at least approximately normal.…arrow_forwardHi could you answer whats blank?arrow_forwarduppose you reject the null hypothesis H0: μ = 101.
