Webb12 maj 2024 · Converting 47 and 53 into z -scores, we get z = -0.95 and z = 0.95, respectively. From our z -table, we find that the proportion between these two scores is 0.6578 (the process here is left off for the student to practice converting X ¯ to z and z to proportions). So, 65.78% of sample means of sample size 10 will fall between 47 and 53.
