Great video, exactly what I needed for some upcoming assessments. Also, so when it comes to the 2 tailed test, the only differences are that you halve the significance level, and that we need to identify whether it's a lower/upper tail test instead of the question telling us?
For Q2 why put the lower bound as any large negative number when the diameter of the circular cardboard disks could not be negative, would using 0 get an incorrect answer?
I don't understand why you square rooted 50 in the first example. as you are given the SD of 1.21 I thought the SD in your calculator would be 1.21/50?
Thank you.. Really it is very much appreciative the way you teach the complex maths...duah from the heart.
Thank you
