The small sample population (30) is selected according to EPSEM, and the variable is interval-ratio. How do you proceed? {The small sample population (30) is selected according to EPSEM, and the variable is interval-ratio. How do you proceed? Proceed with the very small sample population and calculate the sample distribution using the student's t-distribution, gathering a larger sample population to ensure a more normal sample distribution or proceed with the small sample population and use a lower alpha level (0.0001) to compensate
